[maemo-developers] delete-event processing of GtkWindow causes cordump

[From: Zhu, Peter J]

Cumming,


I just redid the test.c in my env and it work now. But if using Hildon,
it crashes as before. Please help try this and use:
gcc crash_hildon_test.c `pkg-config --cflags --libs hildon-1` to build
and run. 

The code is attached.
