After a while of sending and receiving responses to an email (-thread) kmail freezes on composing the next response. When it unfreezes and I change the content (e.g. just type "hello") it freezes again. I dont know how to figure out what exactly makes kmail freeze I already disabled spell checking and removed pictures. I also switched rich text to off. The mail is approx 4.5 k raw source lines long
