I found a message where the signature was described as "detached" in evolution. In addition, it said "Unsupported signature format" on top of the body. The user-agent of the mailer was Gnus. It had two signatures nested actually. The innermost one could be saved without crash. The outtermost only had the yellow or red box below. I tried to clock down my CPU to 333Mhz and go with a _very_ slow keyserver. When it was waiting for the keyserver, I could not view the message. It just said something like "verifying signature.." in the status bar.
If you want to, I can send you the message I tried with, and you can try to reproduce. It looks like this crash is extremely rare, especially if don't have a slow system or so. I'm a bit tempted to downgrade severity one more level, but I'll leave it. It would have been able to backtrace it though! Cheers, Øystein
