When started licq looks at ~/.licq/licq.pid and if it exist and there is programm running with thame pid refused to start. And licq does not remove that file, when exits due to connection lost with X server (normal exit from all(?) window managers).
Пофиксено в licq-1.2.7-alt7 А если /proc недоступен для чтения, то я не виноват :-)
