I think you're off on the wrong track, the failed assertions just look
like your app is doing something wrong. The scenario you describe
should work. The warnings look a bit like gtk_type_init() hasn't been
called (gtk_init() calls this function).  You can't call
GTK functions before calling gtk_type_init(). But maybe it's something
else.

Run in gdb, and break on the first warning.

If it segfaults there's probably a bug in your app somewhere. Try
using gdb to debug the issue. Suggest running the app with the --sync
command line option when debugging Xlib issues.
