Have you emailed the digikam developers? If there is a legitimate problem (though probably more likely to be a false alarm) they would want to know. If it is a false alarm due to Firefox, they may already know (and can reassure you) -- or don't know and need to know.
I want to keep my metadata in the digikam database (only), i.e. not write it to the EXIF data. However, I'm afraid that if I rename photo files or move them to a different folder, digikam won't be able to recognize them anymore and the metadata (ratings, labels etc.) will be lost.
I wanted to try out raw image processing with my Canon EOS 350D (RebelXT). I have been using digikam for about a year now to edit and sortmy photos, so I wanted to see if its (new) raw handling was usable.
Compiling from SVN went relatively smoothly. To avoid the hassles ofhaving KDE pieces in /usr/local, I used the nifty (when it works)checkinstall to build debian packages. Because I have one debianpackage for all of the libs and one for digikam, this conflicts withseveral existing debian packages. Not to fear, just keep removingthings and try dpkg -i again.
