When working in Eclipse I get "Widget disposed too early!" errors, mostly when the auto completion menu opens. This is similar to bug 284042 but has a different stack trace and exception message. -- Error Details -- Date: Sat Jul 18 22:11:16 CEST 2009 Message: Widget disposed too early!

Moving to UI.
This error tends to go hand in hand with the XPCOM error and I'm inclined to believe it's just caused by bug 284042 personally.
I dunno Remy, looks like a Quit has been called and it's trying to shutdown and some widget that's part of the Part is getting disposed too early.

Please attach the log ... usually the exception or 2 that follow the "Widget disposed too early!" exceptions is the culprit. PW

I guess that makes this bug a duplicate.

Sometimes bug 284042 (XPCOM error) happens earlier but not always.
This bug hasn't had any activity in quite some time. Maybe the problem got resolved, was a duplicate of something else, or became less pressing for some reason - or maybe it's still relevant but just hasn't been looked at yet. If you have further information on the current state of the bug, please add it. The information can be, for example, that the problem still occurs, that you still want the feature, that more information is needed, or that the bug is (for whatever reason) no longer relevant.
