That is a known bug in glibc: <http://bugs.debian.org/208428>. There's
a patch in the bug-tracking system, so the chances of it getting fixed
eventually are excellent.

According to the BTS logs, the bug manifests itself if lines in
/etc/group (or any NSS database file) are longer than 1023

(By the way, looking at the BTS page for glibc
<http://bugs.debian.org/src:glibc> would be a more canonical way of
investigating such problems than mailing debian-devel. #208428 is the
very first bug listed on that page; going by its title it'd be hard
for you to miss).

Henning Makholm                     "However, the fact that the utterance by
                           Epimenides of that false sentence could imply the
           existence of some Cretan who is not a liar is rather unsettling."
