$ xscreensaver
xscreensaver: couldn't setgroups to bartvh (1000): Operation not
permitted
xscreensaver: effective group list: [cdrom, audio, video, staff,
plugdev, fuse, netdev, bartvh]
$ dpkg -s xscreensaver | grep Version
Version: 4.24-1
Note that the changelog mentions getgroups, whereas the bug report is
about setgroups.
xscreensaver is trying to disavow write permission into (e.g.) group
"cdrom", and it can't.
Had your group list contained only one element, "bartvh", it would
not have called setgroups at all (see comments in driver/setuid.c).
I don't particularly pretend to understand this crap.
Is the executable setuid?
