I can reproduce this issue but with I get 3 different type of bugs:
1. Unity / Compiz crash as described in the original report
2. Only unity-panel-service crashes
3. Nothing crashes but the icon in the launcher vanished and the app linked to this icon close suddenly (all the instances).
Thanks for the log, I'm setting to triaged.
