client hangs after 'Message contained no data'

[jwaldmann]

I often get this in the lower-left client window

[Errno 32] Broken pipe
"Can't connect to server"
Warning: connection lost.

and at the same time this in the console:

Exception in thread Thread-1:                                                [0/831]

Yup it's a bug that happens sometimes when connections drop
