Two days ago kmail startet to be sometimes (!) *very* slow. Kmail ist working
very much on the harddisk, (top: 80-90% CPU, 30-35% Wait I/O) and I can't
detect what he's doing. -For sure it's not me, because working in that time
isn't possible any more (Open a reply takes round about 5 to 20 seconds, doing
some drag&drop-operations is quite impossible). 

After several minutes everything's fine and everything is working as fast as
always. I haven't done anything during that time.

Working with kmail isn't possible any more (without becoming very angry).

What I have done before: Maybe I reached the limit of 256 folders per
IMAP-account, but at the moment I habe 240 folders and the problem still
exixts. And I added a LDAP-resource in kontact adressbook. I deleted this
resource -- it's still slow. 

What didn't help: Forgetting the whole lokal IMAP-stuff and rebuilding the
lokal IMAP-storage. At first it looked good, but after some time kmail became
slow again.

I know this bug-report is very unspecific. What kind of informations do you
need and how can I gather them?
