Description Vlado Plaga 2009-12-27 00:38:24 UTC 
Version:           1.0.0 (using KDE 4.3.2)
OS:                Linux
Installed from:    Ubuntu Packages

Similar to the report in #218633 I also lost metadata applied to hundreds of pictures.

Experimenting around with generated test images now allows me to give a more detailed description of where a loss occurs:

If you set digiKam to not save metadata in images, then apply a rating or some other tag to more than 201 pictures in one album (directory), and then choose "Write Metadata to images" from the "tools" menu, only up to 201 pictures per album will actually have metadata added.

I checked the results by running "exiv2 -p a", but looking at the files' modification dates should suffice.

I used a new user account, and only generated a few hundred small images using "convert" and a bash script, so that "Write Metadata" did not take too long.

The problem already occurs in digiKam 0.10 (which is the version that caused the trouble for me), and it is independent of the architecture (at least it occurs on both PPC and amd64).

Off-topic: I'm glad I have an update of my digiKam 0.9.4 database with the meta data I now wanted to have in my pictures... so I just need to make sure I call "Album / Write Metadata to images" for all the larger albums in the backed-up version (this worked in my tests), and merge my old and new digicam directories.

Vlado, you refer to "Tools -> Write Metadata to All Images"? "Write Metadata to Images" is in the "Album" menu.
Comment 2 Vlado Plaga 2010-01-02 13:35:04 UTC 
Yes, I mean "Tools -> Write Metadata to All Images"! Sorry giving this bug a misleading title. The function under the "album" entry works with more than 201 images. Can the title be changed?

SVN commit 1069000 by mwiesweg:

Indeed album listing was cancelled after receiving the first package of ImageInfos,
which is typically 201 images.
Use a status variable, reorganize a bit.
