While you are at it, would it be possible please to store the md5
checksum for ignored photos and use them on scan ?
When I last reorganized the directory structure KPA worked like a charm
with two exceptions:
- photos whose md5 checksum changed due to editing the photos
- all ignored photos came back to life, because KPA didn't recognize
them, because no md5 sum is stored for them.
(I ended hand-editing the index.xml to fix with)

(Ok, I guess this is only very slightly connected to the recent
discussion and I should probably enter a report in the bugzilla)
