If your application segfaults just after updating the contents of one of
the children of a top level window you should check your update function
again. This usually happens due to wrong parameters, illegal pointers,
freed objects or similar.

Although I don't know anything about your session management strategy I
don't think the segfault, as described by you, has anything to do with
it. freedesktop.org likely won't help you solving that bug. Generally
speaking there are no particular (technical) problems when dealing with
more than one top level window.

I'd rather guess it's a traditional bug of yours while programming GTK.
Please check your GTK function calls, parameters and validity of handles
again. I suppose you have already verified that it's really the
GtkTextBuffer-update function that causes the segfault and not something
else?
