[Dovecot] dovecot 1.2 latest copy delete etc perfomance slowed down extremly works partly

[Robert Schetterer]

Hi Timo,
with dovecot 1.2
copy delete etc imap funktions
get slow down extremly

log shows that the copy command
is done right but takes extremly log to perform
sometimes goes into timeout

--log

dovecot: Jan 20 15:48:48 Info: IMAP(huber at schetterer.com): copy: uid=5,
box=Drafts, dest=Trash,
msgid=<20090120140432.516062360C0 at master.schetterer.com>, size=748
dovecot: Jan 20 15:48:48 Info: auth(default): new auth connection: pid=28816

Timeout leak: 0x80a9720

---
after restart dovecot the imap function i.e. delete is done
and deleted mails are shown up in i.e the trash folder

any idea whats happening after the last patcheswhich might be envolved?
any hint to get more info out of the logs for debug ?

client was latest thunderbird stable
