agent corrupting .overview/.agentview

[Christoph Rohland]

Hi,

Apparently the agent does not handle the case right when does get the
same article several times:

The first time I experienced this when I applied Simon's patch to
include readedness into the category predicates: As soon as I included
some read articles into the category it came up with corrupted
overview files.

Today I had the same with a standard setup. I investigated some more
and found, that one article was 16 times included in
News/agent/nnimap/unnamed/INBOX/.overview. It also was 16 time in
.agentview, but .agentview was not sorted, .overview was. This
apparently leads to an 'unexpected end of buffer *Gnus agent
overview*'. After sorting and uniq'ing both buffer it worked again.

Greetings
                Christoph

Yes, I've been seeing this too.  However, it should not cause any
problems in itself (other than wasting space).  I'm working on this
tonight.

Ouch, this might explain the problem with re-fetching articles in the
first place.  Thanks for spotting that.
