[Digikam-users] duplicate hashes in digikam 1.7 database

[Elle Stone]

Hi, All,

I noticed several of my images have the wrong thumbnail. A bit of
investigation showed that the problem is that the images with the wrong
thumbnail all have the same (not so) uniqueHash in the database. Why the
images with duplicate hashes pick up the thumb of a different image is a
mystery.

is a recent discussion of hash values, but no problem with duplicate hashes
was mentioned.

Is this an already-posted bug? I have a test database (14 images) with
screenshots documenting the problem, if anyone is interested. 

I checked - md5 sums of the images are all different (and the images look
different - all the same staring raw file but very different renderings).
Apparently digikam doesn't used the entire image file for calculating
hashes?
