Just as a pointer that might or might not be able to explain kim's behavour as described in this thread.
1. Kim is simply made up out of a few bash script that apply ImageMagick's "convert" commandline app to the images whose name ends up on the commandline by virtue of selecting multiple files in Konqueror. Kim depends on ImageMagick, bash and Kdialog, nothing else I am aware of.
2. Not kim's fault, but the bash scripts (if not "all", definitely most) fail silently when the pathname of the files they receive on the commandline contains a space or other non-"abc" character.
3. If you unleash kim on a perfectly good konqueror window that is opened up to any drive/directory mounted to the media:// protocol, kim (and other bash scripts will die a horrible death as you described).
4. Solution: try and open the newly mounted directory through its /mnt/xxx mountpoint - there are no funnies in there.
5. Solution 2: make sure the directoryname the images are in does not contain a space character, replace by underscore if necessary.
