gdk_threads_leave is possible to cause segmentation fault?

[Rúben Rodrigues <ruben_gr live com pt>]

Hi guys,

My application sometimes have segmentation fault error. In debug mode 
and using g_print() i see that the applications stops in 
gdk_thread_leave function.

In gdk manual i see thath gdk_threads_enter and leave has been 
deprecated and alll gdk and gtk+ calls should be made from main thread. 
How we do this? Someone have any example?

Thanks!
