Description of problem:
This time it was NOT - as in most of the cases up to now - , when I pressed "send/receive", but when I clicked on an e-mail I wanted to read. It stood much time advising that it was loading the mail - something evolution does since some weeks, never did it before, but since some time it often takes much time to show the content of an e-mail, and while it is loading I got the message that it was loading the mail - when suddenly evolution crashed.
Evolution crashes many many times a day since I have fedora 19 on my pc. It gives or "killed by signal 6", or "killed by signal 11".
