This bug makes Eclipse completely unusable.

1. Window > Reset Perspective > OK
2. Close the 'Package Explorer' view.
3. Show the 'Package Explorer' view.
4. Select stuff in it. Every time you click an item you will get an error.

Cannot reproduce with I20110524-2200 on Windows XP. I believe the changes for bug 284388 has fixed this problem.
