Hi,

a few times I've head the issue of qgo crashing:
-----
[...]

15 255(W): B5

sendText: A4 158

Not local game.

Not local game.

ERROR: connection closed by host ...
Socket Error

onConnectionError
Destroying IGS connection
Disconnecting...
Deconstructing room
zsh: segmentation fault  qgo
-----

So at some point when it was my turn I wasn't able to do a move anymore, clicking did not do anything in the GUI. A few seconds later (something between 30 to 60 seconds, so around the TCP connection timeout?), qgo crashed with a segmentation fault.

I'm not sure, it seems like either my opponent has left the game or my wifi connection was failing for a few seconds while playing against someone else on IGS.

Cheers, Linus

And here's a calltrace gathered via gdb. It's probably not much use without debugging symbols in qgo, but well, attaching it anyways:
