Re: $drawing_area->queue_draw(); make program crash on some systems

[Guillaume van Baalen <postdoc38 yahoo fr>]

Hello Emmanuele,

My apologies, I thought the original email would appear in the thread. As I wrote in the first email, I have 
a $drawing_area that is a grand-grand-grand child of a $window. When the user clicks on the drawing area, my 
program adds a point (and then paths) on the locations clicked.

To schedule the redrawing, I tried calling $drawing_area->queue_draw();. This works fine on opensuse 13.1 
i586, but crashes on opensuse 13.1 x86_64.

Calling $window->queue_draw(); works fine on both systems, but does not make much sense to me, particularly 
if I ever want to replace it with a queue_draw_area(...).

Anyway, I'll try a GDB trace, and maybe strip all the UI and stuff from my program to have something shorter 
exhibiting what I think is a bug...

Guillaume
