I think I may have found the culprit... I had a thread that was
setting values in the Treestore that called upon the TreeView to
update through the ThreadNotify method... thinking that the
TreeStore wasn't 'quite' GUI-enough to need thread-protection.  But
it seems that way.
I removed all reference preservation and the .Ref() from the Pixbuf
as well as columns and such... and there are no more crashes.
I'll keep my eye open for this occurring in the future, however.
