[gtkada] Tasking and GtkAda -- have you seen this error?

[Nash, D. LTC EECS]

Dear friends,

Apologies in advance if this is a FAQ that I've overlooked.  I'm using
GtkAda 1.2.10, under Gtk+ 1.2.8 on Solaris, and am having some trouble
writing applications which employ tasks which interact with the GUI.  For
example, I can compile and link the double-buffering demo that comes with
GtkAda, but it core dumps when I try to execute it with the following
messages:

Gdk-ERROR **: BadLength (poly request too large or internal Xlib length erro
  serial 90 error_code 16 request_code 6 minor_code 0
Gdk-ERROR **: BadRequest (invalid request code or no such operation)
  serial 91 error_code 1 request_code 255 minor_code 246

GtkAda / Gtk+ seem otherwise to be working with no problems -- I can run
testgtk and all of the other demos without error.  I get the same behavior
(though not exactly the same error message) using the Win32 port, so I must
surely be lacking a configuration of some sort.  Does this seem familiar to
anyone?  Thank you,

Dave
