Hi slocaus,
I guess, there must be somewhere an "addressbook-lock-file" which has not been removed properly.
I have to admit, I do not know where this lock-file is located.
Maybe Ulf do know details?
Slocaus, can you find in the /home/zaurus/kdepim directory ( and subdirs) a file, which name contains "lock" and which size is zero or almost zero?
If you do not find it there, I would have to look for the filename in the program sources.
