Description Andi Clemens 2009-09-09 15:12:49 UTC 
Version:           1.0.0-beta5 (using 4.3.1 (KDE 4.3.1), Arch Linux)
Compiler:          gcc
OS:                Linux (i686) release 2.6.30-ARCH

When I rename an album or move it to another location, the thumbnails don't get updated in the database.
This leads to problems, for example when you call "Rebuild Thumbnails" in "Scan" mode.
It will always recreate the thumbnails for the moved / renamed files, regardless of how often you start the scan.
The thumbs have an unique hash in the database. We only seem to check for the existence of such a hash, regardless of the path that is also associated with this unique hash. I think we need to update the path to avoid this problem.
Sometimes I even don't see any thumbnails after a move, because the old path is still written into the database.

The main problem here is thumbnail rebuilding dialog? Does the last sentence you wrote also refer to this dialog?
Comment 2 Andi Clemens 2009-10-08 01:25:13 UTC 
The main problem is that thumbnail entries are duplicated in the database itself, when using the "Rebuild Thumbnails" dialog...

I actually fixed this issue, but I'm not happy with it. We need to add some update mechanism that works better than the "quickfix" I added.
Anyway this bug can be closed.
