Thanks for the excellent bug report.
I've uploaded 1.12.0-5 which hopefully contains a fix for this crash.
This crash was caused by the server being unable to find the bitmap which the
application wants to use for it's icon, it's not clear why this is happening,
so I would be interested to know if the application icon is correct or not.
