When a runtime exception (such as a NullPointerException) gets thrown from
within a handler method, the entire Gtk main loop freezes.
This patch corrects the problem. The only thing is it seems like the
exception may not be getting re-thrown like it ought to be... the program
no longer freezes but the main loop doesn't exit with an exception either.
Anyway, it's one step up from where it was:
