Hello.
I have a program that has besides the main GUI thread another thread
that creates some labels and pack them into a vbox. Before I do GUI
stuff in the thread I call gdk_threads_enter() and when I'm done I have
while (gtk_events_pending())
gtk_main_iteration();
gdk_threads_leave();
There's no other thread.
But still the program crashes. What could be wrong? Here's the
backtrace:
--------------------------------
Program received signal SIGSEGV, Segmentation fault.
