Troubleshooting Visual Studio 2008 crash when loading a solution

Question

I've downloaded the source for SubSonic via SVN. When I try to open the project in Visual Studio 2008, it converts the solution, loads all the projects then disappears without an error message. Subsequent loads of the solution do the same. If I run devenv /safemode and then open the project it works fine, but I can't use any add-ins.

Any ideas for tracking down the crash?

Edit: In event viewer:

    Category:   None
