problem with programerror outside GPS

hej 

This problem may not beconsideret to be an GPS problem 
it may be an GtkAda problem but anyway here comes

Im an using GPS and i godt this error

raised INTERFACES.C.STRINGS.DEREFERENCE_ERROR : i-cstrin.adb:183

The funny thing is that this error only occour outside GPS. 
When i run my program inside GPS there are no error;

I have traced it too be a call to 

Gtk.Window.Initialize  witch provoke this error. 

And it does not occur in all my programs. 

Anybody got a hint or shall i ask in the GtkAda-list.
