[GtkGLExt] Segfault when terminating application

[Peter Poulsen <peter_poulsen stofanet dk>]

I have tried compiling the simple example that comes with gtkglextmm 
(and other). When they terminate I always get a segfault (its not that 
crucial as it happens when I terminate the application, but still). I 
have noticed it has something to do with the get_gl_context(), for if I 
change it to create_gl_context() it does not segfault (now the 
application does not work, however).

Have anybody experienced the same?
