Fixing the issue by incrementing the recv id correctly.

I've fixed the issue.

The root cause for me was a crash in ButterflyTextChannel._signal_text_received
(UnicodeDecodeError). The message ended up in the pending messages queue, but the current ID did not increase. The attached patch fixes this.

Fixing the crashes in _signal_text_received would also be a good idea
(the UnicodeDecodeError has already been reported). The easiest way to
fix that would probably be using python 3 instead of python 2...
