[Hans Joachim Desserud]

Steps to reproduce:
1. Start lxsession-edit
2. Attempt to close it by clicking the X in the corner.

Expected result:
The program is closed.

Actual result:
Looks like the program doesn't respond for a long while, then it disappears, printing:
Segmentation fault (core dumped)
in the terminal.

I am no longer able to reproduce this issue with lxsession-edit 0.4.9.2-0ubuntu6 on Ubuntu 13.10, thus I believe it can be marked as fixed.
