On Fedora, /usr/bin/emacs is just a symbolic link to
/etc/alternatives/emacs, which is again link to /usr/bin/emacs-23.2. I
suppose Ubuntu has similar setup.
These links confuse cgrulesengd so it is not able to find name of the
executable and therefore move emacs processes to the right group.
Try to use emacs-23.2 in cgrules.conf and run /usr/bin/emacs-23.2 (or
real name of the executable in Ubuntu) instead of pure emacs - does it help?
I'll try to find a proper solution in the meantime.
