Often when i leave my laptop running overnight i am greeted with the kontact  crash handler in the morning. I notice that happens more so when i have poor netconnection for example when i am too far from my wireless router such that i am still connected to it but am unable to get any internet traffic (sometimes even needing to reset my router). In any case kontact should not crash. Backtrace follows...

Application: Kontact (kontact), signal SIGSEGV
