This looks close. Once you remove(iter), iter is no longer valid so
you shouldn't use it any longer. In particular the iter_next(iter)
following remove(iter) is an error. GTK+ might not catch this every
time, but sometimes you would probably get an assertion failure like
the one you see.
I think you can make this work if you get the next iter and save it
before the remove() like this
while iter:
next = self.lststore.iter_next(iter)
self.lstsore.remove(iter)
iter = next
