One of our users report the following error stack trace. I don't have more details about how to reproduce but looks there is some disposed check missing.

Which build was this on? Any ideas?

Comment 2 Marco Maccaferri

2010-08-04 14:43:20 EDT

Ah, sorry, it is 3.5.2 M20100211-1343

Comment 3 Marco Maccaferri

Just a note to say that the bug is present also in version 3.6.2 and apparently also on the latest 3.7.0. My understanding is that ISVPropListener is added to the toolbar manager and never removed on dispose.

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.

If the bug is still relevant, please remove the "stalebug" whiteboard tag.
