[Dovecot] Quota warnings wrong behaviour (1.1.2)

[Włodek Waligórski]

Hi,

I use the latest version of dovecot 1.1.2. Thanks to the excellent docs 
I managed to get everything working so far, but ...

I'm experiencing such strange behaviour when user gets over 90% of quota 
(the threshold is such):
  1. user uses say 89% of his ~/Maildir
  2. message arrives that increases quota usage to 92%
  3. quota_warning is _NOT_ triggered
  4. user deletes the surplus message and gets back to 89% (quota_rule2: 
Trash:ignore)
  5. quota_warning is triggered and quota warning message arrives

So the event gets triggered when user passes the quota threshold, but 
from a "wrong direction". I would expect that message should arrive 
together with the surplus message.

Below I paste my dovecot.conf and "./configure" opts:
