dovecot - Dec 2010 - problem with virtual plugin/index files?

Hello,

Timo: on Oct 29th I wrote

----
with latest 2.0.6 (601065674f74), the following virtual mailbox
is not behaving correctly. I'm quite sure that the problem has not
existed in some earlier 2.0.x (maybe only INBOX as mailbox then
though):

~user/Maildir/virtual/.week/dovecot-virtual contains

INBOX
INBOX.*
-INBOX.Trash
 inthread refs younger 604800

This works as expected for the first time. But later on, also older messages/
threads are included until I delete the virtual/.week/dovecot.index*.
----

Just want to state that this problem still persists with latest
version. Any idea?

Thanks and greetings,
  Lutz

I know there are problems related to this with INTHREAD, but they aren't
very easy to solve and for now I've more important things to do.. If it
seemed to work before, it was due to luck or due to some bug causing an
unnecessary index rebuild. You could set :INDEX=MEMORY to work around
this, but I don't know how much worse the performance would become. Or
you could just manually delete the virtual indexes once a week.
