That condition shouldn't be possible.  Basically what is happening
is that sudo looked up the group by name in a cache (really a
red-black tree) and didn't find it but when it went to insert the
record a few lines later, there was already a record there.  Since
sudo is single-threaded this shouldn't happen unless the gr_name
field in the struct returned by getgrnam() doesn't match the name
that was actually looked up.

You could add some debugging to sudo_getgrnam() in pwutil.c to
compare what is already in the cache to what getgrnam() returned.
