Thank you two for you replies. I will try the gtk debug env later.

Just to refine my original mail. I would understand if I hit a
breakpoint and there is some
graphics stuff going on.

But I just *run* snowstorm under gdb by setting LL_WRAPPER. I have not
one breakpoint
set, neither do I interrupt the program at all.
I just use the viewer and it will just lock up the whole X display
sooner or later.

When I use the viewer without gdb all is fine, no crashes, hang, all good.

Cheers,
