Hmm, dunno how they could be different.  The two collections point to the same place, the only difference is that one is a symlink:

ls -ld /home/paul/Pictures/camera
lrwxrwxrwx 1 paul paul 12 2009-06-08 11:25 /home/paul/Pictures/camera -> /mnt/camera/

Keep in mind that most of these images are 3 or 6 MB raw files.  Also, the for at least half of the 15 hours I was waiting for KDirWatch to (never) finish.  I'm going to go back to my DB backups and reimport again.
