Bug 321061

Description Susan McCourt 2010-07-27 15:27:26 EDT

Win 7, I20100726-2152

I get NPE's on shutdown when I install the model tooling and the platform is shutting down for the restart.

It's happened to me twice now (once last week, once today) and I have yet to spend time reproducing steps or a minimal set of steps to trigger it.

I started with no deltas, synched to CVS, did some real work.
I had also put the problems view in an editor area, split it, and put it back where it belonged.
I had detached the outline view at one point and put it back.
Everything was fine.

Then I decided to install Tom's model tooling, and when I chose "Restart Now" after the installation, I got this NPE.

(I originally reported this problem by reopening bug 319847, but this case is not the same case, so I'm opening a new bug.)

The workbench comes up in a stable state, so this is not a stop ship, I suspect it's similar to the NPE's Tom has seen...
