Version: 1.12.4 (using 4.3.4 (KDE 4.3.4), Chakra KDE) Compiler: gcc OS: Linux (i686) release 2.6.32-ARCH When highlighting text from an email in my sent-mail Chakra froze up, forcing me to do a hard shutdown. Everything was frozen; even Ctrl-Alt-Backspace was useless. I was able to recreate this freeze twice, and don't want to have to try it again.
Without a backtrace, impossible to say whether this is related to kmail or not. (attaching gdb to the kmail process would be a good start if this issue is reproducible)
