My only advise is "good luck" - I spent a fair bit of time try to
fix that function, at one point, apparently without completely succeeded,
but I've since forgotten everything I learned about the text widget.

(GtkTEut is broken, its not, IMO, fixable, so we have a replacement 
in the development version.)
I
 don't see any way that that loop could lock up offhand...

You might want to check the GtkText descendents (In particular GtkExText) 
- to see if they have any fixes in this function.
