Eclipse 3.3
Pydev 1.3.6
Python 2.5
Ubuntu 7.10

I get this after opening eclipse to a project i've previously created.  Shows up in the pydev package explorer. I can make it go away by closing the package explorer and then going to view and opening it back up, then it works fine.

Error creating the view.
