[erlang-questions] VM segfault on exit with wx

[Dan Gudmundsson]

I had a quick look at this, and I have an eternal loop there.

Since erlang is going down it kills all processes, the wx thread can't
send an event to a non existing process and it tries to send an error msg to
a non existing process which fails and it tries to send ... sigh

Will fix in next release.
