--- Comment #1 from René Krell <renda.kr...@gmail.com> --- Important addition: This problem doesn't happen right after system start, but some time after using KMail (after several seconds, minutes or even hours). At the moment I can't see it, but when it happens the notebook's fan is running on higher speed, probably due to a high CPU load. As soon as the problem occurs, KMail doesn't recover from it, so the high load remains instant until the next system restart. I nobody can reproduce this, please give me some hints what outputs to generate and provide, and what to do else to help analyzing. -- You are receiving this mail because: You are watching all bug changes.
