QOwnNotes almost always crash when I close it (openSUSE Tumbleweed with fcitx)

[iclementine]

QownNotes always crash when I close it. I have this problem on openSUSE Tumbleweed. (The smae is on 15.1.) The debug info is uploaded above, but I don't know why. May this will help. Thank you!

Have you installed the debug modules of QOwnNotes? A core dump would be nice.

[pbek]

I cannot confirm this problem on my openSUSE Leap VM, no crashes there. @euneuber can you confirm crashes?

[euneuber]

No crashes in openSuse Leap 15.1 x64

[pbek]

Thank you!

[iclementine]

I generate the core dump file. How am I supposed to use it?

[pbek]

I'm especially interested in just the stack trace of the calls that caused the crash.

[iclementine]

call stack.txt Is this the right information? (I gdb QOwnNotes core_dump_file and typed bt full and saved the results.)

[pbek]

Thank you, that was what I'm talking about. But I think can't see a segmentation fault in the file. Did QOwnNotes crash in that run? What happens if you run QOwnNotes directly from gdb?

[iclementine]

I updated qownnotes and tried again, and catched a segmentation fault now. (I run gdb QOwnNotes, and close QOwnNotes by clicking the cross button of the window. I would get a Dr. Konqi alert that QOwnNotes quited unexpectedly. Sometimes, closing QOwnNotes with Gtrl Q does not invoke that alert.) stack_trace2.txt

[pbek]

Thank you, that part was the helpful one:

Seems that a warning (which isn't the problem) is written to your log panel while the panel is already gone while quitting. I tried to prevent that as good as possible quite a while ago.

Thank you! I'am looking forward to it~

Warning: QFileSystemWatcher::removePaths: list is empty ((null):0, (null))

It's really strange. Not even such a warning is supposed to appear, because there is a check if the list is empty. I cannot even reproduce this warning.

https://github.com/pbek/QOwnNotes/blob/a0c61aa7e7e0a31c2c30a40fdafeaa3ab1acd6fe/src/mainwindow.cpp#L3176-L3181

Other Tumbleweed users seems to have had a similar issue with other apps: https://bugreports.qt.io/browse/QTBUG-68607

[pbek]

As for LogWidget::logMessageOutput, logging to the log widget is disabled when the app is shut down... I don't see a way that it could have caused the seg fault.

[pbek]

19.9.11

• faulty QFileSystemWatcher::removePaths warnings are now ignored, they seem to have caused troubles on openSUSE Tumbleweed

[pbek]

There now is a new release, could you please test it and report if it works for you?

[iclementine]

There now is a new release, could you please test it and report if it works for you?

Thank you! I haved tested it, and it gave the same results. It should a problem of tumbleweed.

[pbek]

You tested 19.9.11? What same result? Did QOwnNotes still crash when quitting with Ctrl + Q? Can you please send a stack trace again.

[iclementine]

You tested 19.9.11? What same result? Did QOwnNotes still crash when quitting with Ctrl + Q? Can you please send a stack trace again.

Yes, quitting with Ctrl Q cause a segmentation fault, too. And I thought of fcitx, maybe it was the reason. Then I uninstall fcitx and its qt5 plugin, the crash disppeared. I would send a stack trace after I reinstall fcitx and its qt5 plugin.

[pbek]

I wonder how fcitx can crash QOwnNotes...

[iclementine]

no_fcitx.txt with_fcitx.txt

Here is the stack trace. Fcitx interacts with Qt5 and qt-5 apps with a libfcitxplatforminputcontextplugin.so at /usr/lib64/qt5/plugins/platforminputcontexts/.

When I've installed fcitx and used a Chinese input method with QOwnNotes, like sunpinyin, google pinyin or rime, QOwnNotes would crash at quitting.

Tumbleweed preinstalls fcitx if the language setting is Chinese, because input method is a necesary tool for Chinese users. (And korean and Japanese users may also need an input method, too.)

[pbek]

The warning Warning: QFileSystemWatcher::removePaths: list is empty ((null):0, (null)) is still in, so it seems fcitx is throwing it.

Do you have the log panel enabled in QOwnNots. If yes, does QOwnNotes also crash if turn it off?

(Been busy for several days..., sorry for a late reply) No, I do not enable log panel in QOwnNotes.

[pbek]

Oh, then I have even less idea of how that crash happens. It really seems to me that fcitx is crashing and taking QOwnNotes with it.

[iclementine]

Oh, then I have even less idea of how that crash happens. It really seems to me that fcitx is crashing and taking QOwnNotes with it.

Also, fcitx is now archived and inactive in development. Fcitx5 is the new version to replace fcitx 4. May be things would be better with fcitx 5.

[iclementine]

I reported the bug to fcitx developers. It turned out to be a known bug.

https://bugreports.qt.io/browse/QTBUG-68607 https://gitlab.com/fcitx/fcitx-qt5/merge_requests/25

Now it is fixed.

[pbek]

Awesome! Thank you very much!
