*** This bug has been marked as a duplicate of 59571 ***

Comment 2 Stefan Xenos

You can reproduce this by leaking an editor presentation as described in bug
59571,  then sending it a property change by changing one of the global
preferrences (I changed both show editor tabs on top and show multiple tabs at
the same time).

I suspect this is a dupe of bug 59571.

Comment 3 Michael Van Meekeren

2004-06-08 14:48:36 EDT

turns out this is not a dup.  using the steps above, the assertion still 
happens after applying the fix from bug 59571

Comment 4 Stefan Xenos

2004-06-08 15:02:11 EDT

To reproduce: 

- open new workbench window
- split and unsplit a bunch of editor panes using drag/drop
- close the new workbench window
- change the "show multiple editor tabs" and "editor tabs on top/bottom"
preferences.

You'll get the assertation failure.

Comment 5 Jared Burns

I get this exception in my target just by exiting and restarting my target. I just cleared my log, 
shutdown, and restarted. When the target came up, it had the above exception in the log. No split 
editors, no new workbench windows, no preference changes.

Comment 6 Stefan Xenos

2004-06-08 15:48:58 EDT

Fixed in head (inspected by Michael)

Comment 7 Stefan Xenos

2004-06-08 15:50:07 EDT

Jared, can you provide steps to recreate this? This will help us verifiy that is
has actually been fixed.

Comment 8 Jared Burns

2004-06-08 16:38:34 EDT

Unfortunately, I can't. I've just seen it intermittently.
