I think what Samuli was trying to say was that the suid bit is dangerous
if you give global execute permissions to the file, because then anyone
can run it as root. The default of rwx--x--- if safe because only root or
a member of the messagebus group can execute it.

My problem was that the messagebus user was not a member of the
messagebus group thanks to a mismatch of IDs in /etc/{passwd,group} - I
don't know whether this is also the cause of the error messages on
Helmut's system.
