_pygi_argument_from_g_value: code should not be reached

[clockworkpc]

Was working on a text file (Haskell actually) when gedit crashed repeatedly on a particular line.

ERROR:/build/buildd/pygobject-2.28.6/gi/pygi-argument.c:1881:_pygi_argument_from_g_value: code should not be reached
Aborted (core dumped)

Thank you for taking the time to report this bug and helping to make Ubuntu better. Please try to obtain a backtrace following the instructions at http://wiki.ubuntu.com/DebuggingProgramCrash and upload the backtrace (as an attachment) to the bug report. This will greatly help us in tracking down your problem.

I get this error as well using the revamped gedit-latex plugin from git.gnome.org.

I don't have time to debug now, but I get an additional line of output before the segfault:

[Andrea Cimitan (cimi)]

It's the SourceCodeBrowserPlugin.

[John M (jwmwalrus)]

@Andrea Cimitan: No, it's not. I have both the gedit-latex and the source code browser plugins from git. I only get that error when opening a .tex file (even wit the source code browser plugin disabled or completely removed).

[Tobias Wolf (towolf)]

I don’t have the browser plugin at all.

[Tobias Wolf (towolf)]

Why is this invalid, Andrea? Different plugins can crash Gedit, that should not be possible.

You conclusion seems premature.

Here's a traceback just using the new LaTeX plugin:

This is caused by multiedit plugin, see https://bugzilla.redhat.com/show_bug.cgi?id=1036235#c10

[Weslley da Silva Pereira (weslley-spereira)]

It worked!
Just turn off the plugin.
Thanks Marv-CZ.

[positivek (anonyhole)]

I also got Gedit to not crash by turning off the "Multi Edit" plugin.

Gedit: 3.10.4

Ubuntu:
Description: Ubuntu 14.04.2 LTS
Release: 14.04
Codename: trusty

[marseille (marseille)]

Thanks! Turning off the mutli-edit stopped gedit 3.10.4 from crashing when I open certain html files with dirty code.

I was getting a slight variation of the error:
