I tried the packages in PPA but they didn't solve the problem, then I decided to go back to the package in Maverick by using the ppa-purge utility (from the xorg-edgers PPA):
sudo ppa-purge docky-core
Finally I ran docky with "docky --debug" for further debugging and the problem was gone (see the output in the attached file). I haven't been able to reproduce the problem since then (with or without "--debug").
My guess is that some file was removed from /etc when I purged the packages.
