_pygi_argument_from_g_value: code should not be reached

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:

It's the SourceCodeBrowserPlugin.

@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).

I don’t have the browser plugin at all.

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:

The same behaviour here.

Note:

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

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

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

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:

$ gedit

El error lo analicé con cierto detalle, pues me ha afectado mucho en mi trabajo, la discusión del mismo es algo extensa, así que publiqué algo al respecto:
