gajim hangs when network link down

gajim tends to hang while the network link is interrupted, for example, a internet uplink disconnect. Unless the timeout is received, the program stopped responding entirely, even the gtk stop drawing the window.
Steps to reproduce
Unproperly stop the network without noticing the system. Like pulling the plugs for example.
