Sorry for the late response. I did some debugging and found the problem. I
installed openSUSE 11.0 and created a new KMail setup. Everything was working
fine and I was not able to reproduce the bug. Then I copied my .gnupg dir from
openSUSE 10.2 to openSUSE 11.0 and suddenly I noticed the 5-10 hang in kmail
which was caused by 100% CPU load of dirmngr. So I looked into the .gnupg
folder and noticed that dirmngr-cache.d/ has a size of 123MB! It contains a
81MB big DIR.txt and miscellaneous files DIR-tmp-$HOSTNAME-XXX.txt.tmp and
crl-XXX.db (XXX are numbers/hex numbers). I removed all files within the
dirmngr-cache.d folder and now the issue is gone. I guess dirmngr parsed one or
all of these files which takes 5-10 seconds and causes the high load.
