[Mailman-Users] Bad error message

I just spent the day fixing what turned out to be a bad qmail install, but
was compounded by a bad error message in mailman. I don't expect any help
with the qmail issue, but I thought people might want to know about the
bad error message from mailman.
Basically, when a message came in from the Internet that was bound for a
mailman list, I was seeing the following message in my qmail logs:
===================================8<---------------------------------
delivery 13: deferral:
Failure_to_find_group_name_nofiles.__Try_adding_this_group/
to_your_system,_or_re-run_configure,_providing_an/
existing_group_name_with_the_command_line_option_--with-mail-gid./
===================================8<---------------------------------
It was driving me nuts because the 'nofiles' group does exist in
/etc/group and was being used by some of the qmail processes. After much
digging around, I finally found that the message was coming from the
'mailman' program itself. In src/common.c, line 142, there is a fatal()
call in 'check_caller()' if the caller's GID fails to resolve to a name
(getgrgid() returns a NULL). The error message though is misleading. I
thought that it had a group name (nofiles) and couldn't resolve it to a
GID. Since there was a 'nofiles' group, I didn't know what was going on.
As it turned out, the qmail delivery program was running under a GID that
didn't have a group entry and was thus triggering the error.
I think a better error message would be something like:
"Failure to find group name for GID %d:...". Once I changed the message
to that, it was easy to see what was going on.
