I can confirm a general problem, also when using IMAP.  When doing _any_ operation \
that involves a large amount of mail (perhaps 500+), kmail regularly hangs or crashes \
or otherwise fails.  There may be several separate underlying issues, but the general \
result is the same.  

In my case, we have monitoring apps that are known to go haywire occasionally and \
flood me with 1-2k mails.  This usually means I have to fire up almost any other mail \
client to handle it, because kmail will inevitably crash.

Could this have something to do with the progress window?  Creating a separate \
progress bar for every mail being moved/deleted seems like a really bad thing when \
one has to delete 2000 mails... (Although these problems don't appear with local \
mailboxes, only IMAP)

Some results when doing the following actions on roughly 300 - 500+ mails in an IMAP \
box (servers have been cyrus, dovecot and exchange)

Delete (move to trash) - Hangs fairly quickly, usually have to kill 
Shift+Delete - Seems fine at first, then UI hangs (over 30 minutes on 1500 mails, \
eventually had to kill -9) Apply filters (Ctrl+J) - Any attempt to do this on more \
than about 150 mails results in hangs, crashes and/or lost mails. This applies to \
every version of kmail I've used for a couple years.  I've disavowed IMAP filtering \
completely. Move IMAP -> Local - Usually works ok.  Minor hangs w/ 1500+ mails.
Move Local -> IMAP - 50% chance of crash or hang
Viewing/Refreshing any large folder of 1k+ mails - about a 10% chance that the list \
view will go blank.  Can usually fix this by unfocusing/refocusing the large folder.

If there is any hard data you would like, let me know (doing a debug build as I write \
this).

Currently on
KDE 3.5.6
Kmail 1.9.1
