A problem that I have had with kmail in kde 2.0 and am now having with kmail in kde 3.0.3 is that it takes up lots of CPU time when launching gpg.
When I do an operation that causes GPG to take some time (IE re-calculating the trust db because new signatures have been received for some keys) then kmail apparently goes into a spin loop waiting for a response from gpg. The result is that for some minutes kmail gets 50% CPU time and gpg gets the other 50%. I then tried kill -stop on the kmail process, gpg then used >90% CPU time until it finished it's work and I then did kill -cont on kmail and everything was fine. Is there some way to reconfigure kmail to make it behave better? Or is it just buggy? -- I do not get viruses because I do not use MS software.
