Bug#1067648: freeciv-client-qt: segfault upon connect to a server in ___pthread_mutex_lock

[Jeffrey Cliff]

Package: freeciv-client-qt
Version: 3.1.0+ds-1+b2
Severity: important

Dear Maintainer,

what should happen

when you hit 'connect' to server for online play, it should either
connect, or fail to connect: but not segfault & crash.

game is kinda unusable if that's where it crashes.

what happens:

segfault in
