tooltips problem in GTK+ 1.2.5

[Damon Chaplin <damon karuna freeserve co uk>]

I keep getting this warning when tooltips pop up, in GTK+ 1.2.5:

Gtk-CRITICAL **: file gtkcontainer.c: line 739 (gtk_container_dequeue_resize_handler): assertion `GTK_CONTAINER_RESIZE_PENDING (container)' failed.

I can see this in testgtk, in the tooltips demo.
Move the mouse back and forth between button1 and button2 - the warning is output
every other time a tooltip pops up.
