I'm guessing here, so ignore me if I'm wrong.

xander, you're using the tktext port and you simply subclass it.  The
only initialisation happening then is the `init' function.  This will
not initialize the `text_buffer->tree', since the tree is initialised
in `new'.  Unfortunately, you cannot really use `new' to initialise
your subclass, and even worse, you cannot update the tree yourself
since the btree is not public.

I send a patch to gtk-devel a little back[1], that moved the
initialization to a `construct' method, but the patch has not been
applied.
