[Licq-main] undefined symbol in licq_qt-gui.so

[Alexander F. <fi...@we...>]

Hello,
I have just compiled licq 1.2.7 on debian testing (no errors).
But now I can't run licq. I get the error message:

13:23:13: [WRN] Licq: Ignoring stale lockfile (pid 18814)
13:23:14: [ERR] Unable to load plugin (qt-gui): 
/usr/local/lib/licq/licq_qt-gui.so: undefined symbol: 
_ZN7QWidget5eventEP6QEvent.
13:23:14: [WRN] This usually happens when your plugin
       is not kept in sync with the daemon.
       Please try recompiling the plugin.
       If you are still having problems, see
       the FAQ at www.licq.org

Whats the problem and what can I do?

Thanks for help,
Alex
