That stacktrace is after replacing the search toolbar button with a dropdown (bug 72322). So it is not in I20071029-0010. I reverted the change from bug 72322 again to wait after M3.
Since we no longer ask for the menu creator up front, asking at dispose time was activating a similar set of plugins to bug 136397 So if we don't ask for the menu creator, don't dispose it. PW
Since DebugUIPlugin was exhibiting the same behaviour (actived on shutdown) for the same reason, I've verified that this no longer happens in I20071101-0010 PW
