Subject: need help on: Linux Gnome2 Glade Cairo callback problem

Hi,
I have a Glade project main app window with a toolbar and 4 
'drawingarea's, into which I draw some test images using Cairo.
After anywhere between 50 and 100 drawingarea updates I get the 
following message when clicking on a toolbar button.

cairo_test_2.rb:147: warning: GRClosure invoking callback: already destroyed

Before the 50-100 drawingarea updates, the callback works fine.
Could anyone possibly tell me, or offer an opinion as to why the 
callback is getting destroyed?
All I am doing is updating the drawing areas and clicking on a toolbar 
button.

I use Ubuntu Linux, Gnome2, Glade2 and Cairo of course.

Thanks, Mike
