Hi,
I have been trying to run a simple example for libglade and it
fails to create the xml interface widget. I get a segmentation fault
in the gtk_widget_show function when it does
g_return_if_fail (GTK_IS_WIDGET (widget));
It goes through to the last child in the widget tree and then gives me
an error. I tried using the debug in glib but could not understand
what it meant. It fails only when i run a cross compiled version with
directfb backend. On the other hand if I run the example natively with
the x11 backend then it works. Please let me know as to how I can
further debug and identify the problem.
Thank you
Pradeep
