Archiving fails when creating new file

[Angelo Turetta]

See bug 108837, it says fixed in 2.0b4, but something related to it
happened to me in 2.0b6, freshly installed on a FreeBSD 4.1-STABLE machine
(I mean no upgrade from previous mailman version).

Basically, when the archiver has to create an empty file, it goes on but
then fails while trying to find the LF: if the file il empty, it cannot
seek one char before the end of file. I guess the error checking code that
should protect the seek statement doesn't cover all the cases for FreeBSD.

The net effect is that delivery of messages to subscribers is postponed
until I write a LF to the file.

I can test patches in case you need.

Here is an excerpt of the mailman error log:

Oct 06 20:45:05 2000 (1308) Archive file access failure:

Hope this helps
