Which build are you using ?
I'm using Eclipse 2.1 Win32.
Fix for bug 20435 was insufficient. A NPE can still occur in your scenario. The background indexer likely was in the middle of crashing when this problem occurred. Exiting and restarting Eclipse should make it work again (we have some index recovery support).
Correction to my first post : Deleting the metadata directory actually works for some time. Restarting eclipse has never been able to correct the problem.
Fixed in latest (3.0 stream only)
Verified.
