Please upgrade to latest upstream version of apply the above patch.

Bah, 0.2.0.32 that should be, of course...

Comment 4 Enrico Scholz 2008-12-09 13:35:52 UTC

fwiw, this bug never affected any tor version shipped by fedora.
There was always a patch like

http://cvs.fedora.redhat.com/viewvc/rpms/tor/F-7/tor-0.1.1.26-setgroups.patch?revision=1.1&root=extras&view=markup

dropping supplementary groups.
