I suspect a bug in libutouch-geis cleanup code, but still investigating it. I've recompiled libutouch-geis with debugging enabled, and stacktrace now reveals more details - see attached stack trace.

I've confirmed with Stephen M. Webb that they discovered a problem in geis cleanup code and are currently working on this. Linking this bug to utouch-geis then.

The bug seems pretty much alive using libutouch-geis1 at version 2.2.8-0ubuntu1. Proper login to ubuntu 3d is still impossible with compiz segfaulting after getting this error subscribing to gestures. Ubuntu 2D works like a charm though.
