Build id: N20081102-2000

Synchronize with HEAD.
About every 2nd or 3rd attempt to compare a file, an error dialog opens and the compare editor does not open.

Here is the stack trace from the .log file:

Comment 1 Steve Northover

Might just be a bug in Eclipse, not necessarily cocoa.  Does it happen every time?

Comment 2 Carolyn MacLeod

2008-11-03 20:39:50 EST

No - every 2nd or 3rd time.

Comment 3 Kevin Barnes

2008-11-04 09:49:58 EST

I've never seen these errors and I use the synchronize view on cocoa a lot. I'm going to move this to Team for comment. Maybe they can give us a hint at least.

Comment 4 Carolyn MacLeod

2008-11-11 14:16:34 EST

I updated my Mac, and the problem persisted.
I got a newer version of Eclipse Cocoa, and created a new workspace, and the problem went away.
I'm going to close this bug, because it can't be replicated any more.
