Gedit crashes on opening text file

[zzarko]

When trying to open certain text files, Gedit crashes for me. When a file crashes Gedit, the same thing happens when clicking on file or opening it from command line. It also doesn't matter if Gedit is already started or not (if it is started, opening such a file results in lost work on all unsaved files). As an example, in the attachment is the text file that always crashes Gedit for me. Here is the output when starting from command line:
------------------------
gedit RetroCollection.gcs
**
ERROR:../../gi/pygi-argument.c:1583:_pygi_argument_to_object: code should not be reached
Aborted (core dumped)
------------------------
Opening file in other editors is OK (tried with Geany and internal editor from Double Commander). It might be of importance that I have several plugins for Gedit from Ubuntu repository installed and active.

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.

Well, I have disabled gedit crash reports a long time ago, and I don't get the dialog explained in the link you provided. But, I did ran gedit inside gdb and the backtrace output is in the attached file. I hope it helps. If not, how to re-enable crash reports for gedit?

[Sebastien Bacher (seb128)]

the backtrace is not really useful, but the issue is in python code and gedit doesn't use it by default, could you try to disable plugins and see if that helps?
