iPhoto 4 unexpectedly quits when opened, Insufficient disk space in iPhoto 2?

iPhoto 4 unexpectedly quits when opened: "... delete
1. Thumb32.data
2. Thumb64.data
3. ThumbJPG.data"

This fixes:

1. Insufficient disk space when exporting
2. Quit when open

I'd guess it would fix the disk space problem for iPhoto 2 as well. That problem is apparently due to thumbnail corruption.

update: this didn't work for me. I had to use Panther Cache Cleaner to do a deep cache removal. See my posting of 5/1/04.
