We've run into that, too, while running aptitude-robot --which also
calls "aptitude purge ~c" in our case (via some trigger.post).
We suspected it may be related to multi-arch. Does your box on which
this happened use multi-arch? (Or is it the same box as in #724032 and
#724034 which does not use multi-arch according to #724034?)
It may be related to http://bugs.debian.org/724032 and
http://bugs.debian.org/724034. Actually I already had this in mind,
when you reported those two issues.
Without looking at the code, just at the symptoms, there are multiple
ideas where this could come from -- all of them would be bugs:
* aptitude's knowledge about which package has been only removed and
which has been purged got out of sync with dpkg's knowledge.
* It doesn't correctly handle multi-arch correctly on the ~c pattern.
If your machine isn't multi-arch, this idea could proven wrong now,
which would narrowed the source for the issue.
* For some reason aptitude's "~c" pattern matches also purged
packages, not only removed packages. (This may be the same thing as
the first idea, just seen from some other side.)
I remember that Elmar Heeb (Cc'ed) found a reliable way to get rid of
this state, but at the moment I can't remember it.
Regards, Axel
