Your complete test code (or attach your test files):

We have 3 internal handlers for mousedown event: one preventRealEventHandler and two (somehow) downHandler from StatusBar._bindClickOnce. preventRealEventHandler works fine and the first downHandler calls removeInternalEventListener. That causes the error.
For me it looks like we should handle such a situation when one handler removes itself during execution.
