           Summary: "Write Metadata to images" only modifies the first 201
                    files in any directory (album)
           Product: digikam
           Version: 1.0.0
          Platform: Ubuntu Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
        AssignedTo: digikam-devel at kde.org
        ReportedBy: rechner at vlado-do.de


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.
