gedit segfaults on filebrowser sidepane use

[Marcel Stimberg]

This was originally reported by fabrg in bug #926858.
I could reproduce the crash with Ubuntu 12.04 following his instructions:
Steps to reproduce:

1. Open gedit and display File Browser (side panel)
2. Open a structure folder with some folders and files (i suggest you /home/), and expand some folder till you see some files, like
-- /afolder/
--------afile
--------afile
-- /afolder/
--------afile
--------afile
--------afile
3. click "refresh view" button
4. the structure should collapse automaticaly. if not, try to refresh again untill it does. (probally gedit will crash)
5. when the folder collapse, expand it again.
6. repeat steps 3 to 5 till gedit crashes.

Possibly a duplicate of bug #809609, I'm waiting for the apport retracing.
