[Photo and Tile Images] 12.12 is crashing in Ubuntu

[mt-from-sf-to-gh]

During my testing, Ubuntu 12.04 crashed with this log entry in the Eclipse console:

mytourbook: /build/buildd/cairo-1.10.2/src/cairo-surface.c:637: cairo_surface_destroy: Assertion `((*&(&surface->ref_count)->ref_count) > 0)' failed. Aborted (core dumped)

I can't currently say exactly when the crash occures, I've not much Linux experience and did not find a dump file.

If your Linux is crashing when using the new feature to sync photos and tours, report it in this bug tracker, hopefully with a Java stacktrace.

Hello Wolfgang, can you reopen this bug? It's being a problem for me on Gentoo 64bit, at least since 14.10 - mostly random, hard to reproduce crashes, which would sometimes produce a stack trace file. Now with 15.3.2, the crashes seem to be much more frequent, but I have yet to see some debug info generated.

I attached one log file from 15.3.0.

I also have a core dump from 14.10 while I tried running under gdb, but that file has almost 1G. If you think it would help, I can upload it somewhere.

I'll be happy to help debugging, I use Linux and Eclipse everyday for C++ development. Last time I touched a Java code was probably around 2009, but I can give it a try :-)

FYI, it also happens with cairo-1.14.2:

java: /home/portage-tmp/portage/x11-libs/cairo-1.14.2/work/cairo-1.14.2/src/cairo-surface.c:928: cairo_surface_reference: Assertion `((*&(&surface->ref_count)->ref_count) > 0)' failed.

The crash occures in the Cairo code, when I google for "eclipse crash cairo" I saw a solution by setting these in the .ini file (can also be set in the commandline):

-Dorg.eclipse.swt.internal.gtk.useCairo=false -Dorg.eclipse.swt.internal.gtk.cairoGraphics=false

Can you check if this works for you ?

This is the code where it crashes:

I suspected Cairo as well, but didn't find the settings you mentioned. Your Google-fu looks strong :-)

With those settings in the ini file, I still get a cras, but with a different error (attached). To crash mytourbook, I have to randomly click many things. It usually takes a couple seconds to get there.

Also - 15.3.0 and earlier sometimes generated a stack trace file (like the one I posted earlier), but 15.3.2 never does (I tried about 50 times today). Any idea why?

Posting this here for future reference: It would be nice to know how can I "run it with the --sync command line", and "break on the gdk_x_error() function". I tired the tips here http://www.sourceware.org/ml/gdb/2009-12/msg00095.html to no avail. The I found someone who also doesn't know http://blog2.vorburger.ch/2014/08/java-8-swing-related-jvm-crash-on-linux.html (last paragraph).

A bit more googling got me here https://bugs.eclipse.org/bugs/show_bug.cgi?id=183421 and https://fedoraproject.org/wiki/Java/StackTraces?rd=JavaStackTraces

With the modified settings file even 15.3.2 crashes much less than before, if I don't actively tru to crash it, I can use it for whatever I need, so the bug moved to the "mild annoyance" area. I'll get back to it when I have some time to read that Fedora wiki page.

(Edit: reflecting on all that, it seems I might be hitting a different bug now)

Just for the record - this is still an issue. Working with the 2D map will trigger this error sooner or later.

It might be in fact this bug in Cairo https://bugs.freedesktop.org/show_bug.cgi?id=91967 I tried to apply the patch to Cairo mentioned there, but it still crashes, just with a different error
