Feedback on gnome-devel-demos/3.14/gmenu.py.page

[John Coppens <john jcoppens com>]

Hi guys,


I'd extract a minimal program from the example, and always had a Segmentation fault.
After experimenting a lot, I copied the exact code into geany and got the same
segfault:

$ /bin/sh ./geany_run_script.sh
./geany_run_script.sh: line 5: 16418 Segmentation fault      python "gio_menu_0.py"

Geany removes the script after a run, so I ran the code from a terminal:

$ python gio_menu_0.py
Segmentation fault

Running in gdb:

Program received signal SIGSEGV, Segmentation fault.

Python is 2.7.6, glib 2.40, introspection 1.40

Hope this helps
