Is this related to rearanging launchers? Since last update 3.6.2 to Unity, when i try to rearange app lauchers, Compiz crashes without even offering option to restart process...

[Jay Taoko (jaytaoko)]

Cannot reproduce. Also, need more info on the action that was being performed when the crash happened.
 Please, try the latest release of Unity and report if this bugs still happens.

@Jay: can you sync to revert all tasks? (you didn't revert the nux downstream one) when reverting to a previous state? You fooled my script ;) Setting back to Incomplete :)
