Thanks for the report Allan. Now that you point this out I can see that
there are a bunch of them. I've marked the two you reported and a bunch
of others as 'safe' since they can affect the marks or update the view
(which could also trigger callbacks).

The fix is currently in the darcs version:

http://darcs.haskell.org/darcsweb/darcsweb.cgi?r=gtk2hs;a=commit;h=20070211194249-b4c10-1f5d01efa21b3132b9af07307756612c51c82c10.gz

It fixes the problem in the example you sent, it'd be great if you could
check if it fixes the issue in your real app.

Instructions for getting and building the development version are here:
