This bug affects me too for various files. I was also able to reproduce the result with the attached example file. 

I'm on fully updated f20.
Gedit version 3.10.3.

This bug is having huge impact also my work-flow. I use gedit as default text editor and if I have several tabs opened, loading one of such crashing-files, makes all my work disappear.

If there is any information I can provide to help solving this bug, please let me know.

Not even sure it is a gedit bug or Python gobject bindings bug.

I opened the example file in gedit with gdb. This is what I got:

(gdb) run

Ciao Luca, the first thing I would try to do is to pinpoing if the problem is related to a specific plugin you are using

It seems to be related to the Trailing Spaces plugin.

When I turn it off, the example file does not crash gedit (it just opens with the warning "There was a problem opening the file ..." and it points out that the file has some invalid characters). Other files that previously crashed gedit open just fine.

Can anyone confirm this?

I don't have the "trailing spaces" plugin, and when I open the example file gedit does not crash, but shows the "There was a problem opening this file..."

Hi Paolo,

it was my first thought when I saw python in error message and renamed plugins directories, without success.

This time I disabled plugins one-by-one in preferences dialog and... Bingo :)

Probably I did something weird the first time I tried.

Tomas, on my system the culprit is Multi Edit plugin.

I wonder if this could be due to some changes in pygobject and due to some kind of mismatch between the .pyc files included in the plugins' rpm and a new version of pygobject...

Plugins are stored in /usr/lib64/gedit/plugins/, but first time I tried by renaming directories, I only renamed /usr/share/gedit/plugins and .local/share/gedit/plugins. This explains why I didn't find it was a plugin causing the crash.

My rpms are:

gedit.x86_64                         2:3.10.3-1.fc20                   @updates
gedit-plugins.x86_64                 3.10.1-1.fc20                     @updates

Anyway, tried to remove all *.pyc and *.pyo files in multiedit folder and recompiled with "python -m compileall ." (is it correct?). Same crash.

OK, I can confirm that the bug is caused by Multi Edit plugin.

Once I disable the plugin gedit no longer crashes but detects incorrect character in the file.

This message is a reminder that Fedora 20 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 20. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as EOL if it remains open with a Fedora  'version'
of '20'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version' 
to a later Fedora version.

Thank you for reporting this issue and we are sorry that we were not 
able to fix it before Fedora 20 is end of life. If you would still like 
to see this bug fixed and are able to reproduce it against a later version 
of Fedora, you are encouraged  change the 'version' to a later Fedora 
version prior this bug is closed as described in the policy above.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events. Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.

Fedora 20 changed to end-of-life (EOL) status on 2015-06-23. Fedora 20 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.

If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version. If you
are unable to reopen this bug, please file a new report against the
current release. If you experience problems, please add a comment to this
bug.

Thank you for reporting this bug and we are sorry it could not be fixed.
