Comment 1 Prakash Rangaraj CLA 2011-03-10 05:10:22 EST 
Markus,

       How did you get this? I'm not able to reproduce this.
Comment 2 Prakash Rangaraj CLA 2011-03-10 05:17:44 EST 
Added the check and fixed in HEAD.
Comment 3 Prakash Rangaraj CLA 2011-03-10 05:28:34 EST 
Fresh workspaces, workspaces stored with current I Build or 3.6 build open fine without any exception. One possibility for this exception is when you try to open a workspace created with previous I Builds.
Comment 4 Markus Keller CLA 2011-03-10 05:43:34 EST 
Yes, I selfhost on every available build, and this happened in my main development workspace.

This should be fixed for M6, since it makes the affected workspace unusable. And the fix should be reviewed.
Comment 5 Boris Bokowski CLA 2011-03-10 09:45:57 EST 
I've reviewed the change and it looks safe.
Comment 6 Remy Suen CLA 2011-03-10 09:56:17 EST 
Sorry, dunno what happened there. Was just trying to CC myself.

Please review the bug's history to see what happened before I screwed up.

Comment 7 Markus Keller CLA 2011-03-10 10:08:46 EST 
I deployed HEAD of o.e.ui.ide into my install and this solved the problem. Thumbs up for a rebuild.
Comment 8 Prakash Rangaraj CLA 2011-03-17 04:17:50 EDT 
 Marking as fixed.
