This means the object passed to gtk is not a GtkText. Under gtk--, this
kind of errors should not happen. Can you give a small example code which
shows this problem? (I dont know how it would be any way different if one
does it inside a callback, shouldnt be..)

Nope, the error happened inside a cast which gtk checks.

Looks like a bug in gtk-- to me, but cant be sure without more information...
(I think I should look into Gtk_Text more later today...)
