asterisk users - Jun 2003 - Gastman and New Extension

I finally got Gastman to compile but I get a bunch of "failed 
assertions" when I run it and attempt to make a new extension. I have 
latest CVS on Mandrake 9.1. Last error is:

(gastman:22534): Gdk-CRITICAL **: file ../../gdk/gdkdraw.c: line 311 
(gdk_drawable_unref): assertion `GDK_IS_DRAWABLE (drawable)' failed

Other errors are like this one. I apologize if this has been addressed 
previously but a quick search in the list turned up nothing. Any quick 
ideas?
