gedit crashes on autocomplete with SIGSEGV in gtk_text_iter_get_buffer()

[Seth]

When attempting to use gedit's standard autocomplete functionality (e.g. via the included "snippets" plugin), gedit crashes.

Steps to reproduce:

* Make sure you are on Ubuntu 14.10 or 15.04.
* Open gedit and enable the "snippets" plugin.
* Save a new document as "crash.py"
* In this document, type "def" and then press "Ctrl-Spacebar" which is supposed to activate the snippet autocomplete. Instead, gedit will crash.

I get this same crash following the reporters instructions in a Utopic VM.

FYI I am also getting this crash using the latest Ubuntu 15.04 (see attached).

Thank you for taking the time to report this bug and helping to make Ubuntu better. The issue you are reporting is an upstream one and it would be nice if somebody having it could send the bug to the developers of the software by following the instructions at https://wiki.ubuntu.com/Bugs/Upstream/GNOME. If you have done so, please tell us the number of the upstream bug (or the link), so we can add a bugwatch that will inform us about its status. Thanks in advance.

It's absolutly not just for Snippet ! It's for all plugin that add "completion" feature. When I uncheck "Snippet" but let "GDP Completion" it continues to crash.

If I unckeck all plugins with completion, it works again. Never crash.

[RastaPopoulos (flbl)]

And how to work again, when we are just basic users who use the package version of Gedit ? Is there a fixed package ? a PPA ?

Or I just uncheck all completion waiting a classic update ?
