That's what I would expect ;-) I guess I found a bug then...

It's hard to say exactly as I'm using JNI (which makes debugging a bit
harder) and don't have the debug versions of the libraries installed at
the moment. I guess I should try to get everything running with the
debug versions of the libraries and see what's going on. For now, I just
set a default handler and it doesn't crash that way. I'm not sure when
I'll get a chance to debug this properly though as I'm under a fairly
tight deadline at the moment and setting the default property change
handler fixes it for me for now...
