Package: fetchmail
Version: 6.2.4-1
Severity: normal

Consider severity: important
Justification: fetchmail won't retrieve mail
As this seems something specific to my situation, I'm not sure it's
justified.    Your call.

The problem is important to me, though :)

The following excerpt from a debug-run of fetchmail shows the problem:
/etc/init.d/fetchmail: Stopping the service...

/etc/init.d/fetchmail: End of service run. Exit status was: 139
------------------------------------

This is quite strange, because it was just working.  It also appears
to bomb with /etc/init.d/fetchmail restart, i.e., the problem is not
specific to debug mode.

The error is reliably repeatable.

This follows a rather intense period of activity mucking with
mailfilter and fetchmail settings.  I had just had my first successful
run of the combination when this problem arose.  The steps in between
success and failure were these:

Edited fetchmailrc to remove the uidl option.  (I was trying to get
some old mail off the server).  I did this as root.
Attempted debug-run produces
File /etc/fetchmailrc must be owned by you.
I did chown fetchmail:nogroup /etc/fetchmailrc (not sure what it was
before)

Another debug-run.  mailfilter ran successfully, deleting one
message.  fetchmail initiated dialogue with pop3 server and then
failed as in the above log (which is from a little later).

I was running fetchmail and mailfilter pretty frequently, so they may
have stepped on each other.  The frequent accesses to the mailbox on
the server may have put it in a bad state.
