This fix stops the crash, but I'm unsure as to it's correctness. Nothing in the
gtk docs indicates that we don't own a reference to the returned window, yet
the symptoms of the bug seem to indicate that's the case. Will investigate
further
Comment 2 Ismael Juma 2005-12-17 17:56:12 UTC 
I think it makes sense that the TextView would own the GdkWindow, even if it is
not stated in the documentation. Patch looks good from my side.
Comment 3 Adam Jocksch 2005-12-19 15:08:16 UTC 
Will commit above patch to CVS HEAD.
