Meld crashes

[ArekPiekarz]

Summary: Comparing in Meld doesn't work, because it cannot find g_getenv.

Additional info: Package version mingw64/mingw-w64-x86_64-meld3 3.16.4-1

Steps to reproduce:

1. Launch meld from terminal.
2. Click "File comparison" in the middle.
3. Click "Blank comparison" below.

Expected result: Meld should show two empty columns to insert text to compare.

Actual result: Nothing happens in the GUI while it the terminal the errors below are printed.

(Note that some parts are in Polish, I tried changing the language to English by exporting LC_ALL and LANG environment variables set both to en_US.UTF-8 or C, without success. Translation: "Nie mo▒na odnale▒▒ okre▒lonego modu▒u" means "Cannot find given module" "Nie można odnaleźć określonej procedury." means "Cannot find given procedure.")

The error log:

$ meld Couldn't bind the translation domain. Some translations won't work.

Additionally when Meld closes, it prints these errors:

It's a glib 64bit only issue and is fixed in upstream master. Should be in glib 2.54.

The i686 version should work (or at least not fail in this way..)

https://bugzilla.gnome.org/show_bug.cgi?id=780634

[ArekPiekarz]

@lazka Thanks for info, the i686 version crashes when the same steps as above are executed, error log:

$ /mingw32/bin/meld Couldn't bind the translation domain. Some translations won't work. [Error 126] Nie mo▒na odnale▒▒ okre▒lonego modu▒u Couldn't find colour scheme details for meld:current-line-highlight-background; this is a bad install

[mati865]

Both 32 bit and 64 bit versions of meld work for me despite the error, output from 64 bit:

MINGW64 ~

Probably there is some dependency missing.

[lazka]

I can reproduce the problem when starting meld, selecting "Version control view" and clicking the "Compare" button.

[mati865]

Okay, reproduced with updated packages.

[mati865]

I don't see what is wrong:

[lazka]

I don't think the last error is related to getenv. Next glib will also expose g_getenv without the utf8 suffix so it matches with the GIR data and can be looked up by bindings, so that this works: python2 -c "from gi.repository import GLib;GLib.getenv('foo')"

[tylorr]

I just installed the 64bit version of Meld and am getting the same errors as the original poster, is there any progress on this issue or a possible work around?

[fabiangreffrath]

This fixes the issue for me:

 cp /mingw32/share/meld/styles/meld-base.xml /mingw32/share/meld/styles/meld-dark.xml /mingw32/share/gtksourceview-3.0/styles

[mikofski]

@fabiangreffrath yes, that did the trick! Except for me I'm in mingw64 so

cp /mingw64/share/meld/styles/meld-base.xml /mingw64/share/gtksourceview-3.0/styles
cp /mingw64/share/meld/styles/meld-dark.xml /mingw64/share/gtksourceview-3.0/styles

I'm still getting a Python 3 traceback on line 315

Traceback (most recent call last):
  File "C:/Users/mikm/AppData/Local/msys64/mingw64/bin/meld", line 315, in structured_log_adapter
    message = GLib.log_writer_format_fields(level, fields, True)
UnicodeDecodeError: 'utf-8' codec can't decode byte 0x93 in position 105: invalid start byte

Also if I use meld . in a git repo, no luck, even with git install using pacman. But of course these are different issues!

Thanks!

[galkinvv]

About last traceback in structured_log_adapter - it appears on meld running over pygobject-win32 too and is mostly harmless (except that log messages are loosed). I'm using meld with those messages for several months. This exception raises in log writing callback and execution continues normally.

Also after installing both mingw-w64-x86_64-meld3 and git via pacman I found /mingw64/bin/meld . in a simple git repository has a big problems - (repository view opens sometime s empty and double clicking on file fails)

But if git for windows is installed in windows PATH (like C:\Program Files\Git\cmd\git.exe ) and meld is executed from cmd like D:\apps\msys2\mingw64\bin\python3.exe D:\apps\msys2\mingw64\bin\meld . repository view works fine

[lazka]

I think #3882 by @galkinvv fixed the style related errors and the above workarounds are no longer needed.

the gio criticals and the logging errors are still there though.

[lazka]

Since @galkinvv is now active upstream, I think we can close this. Thanks everyone!

[ComputingFroggy]

I am still affected by this bug running meld through git bash ! When I run meld on windows shell, I do not get any error messages.

[Biswa96]

What error are you seeing?
