[sylpheed:30970] segfault while opening pgp signed mail

[Attila Kinali]

Moin,

I just encountered a segfault with sylpheed 2.4.0beta4.
It happens when i try to open a certain mail that is
pgp signed but whos key i don't have. It comes from
gpgme_op_verify_result() returning zero.

System is a linux 2.6.x (debian/testing) on amd64
(64 bit enviroment). Bug is also present in 2.3.0beta4
sylpheed.log doesn't show anyhting interessting. Last
entry is the read of the flags in the imap directory.

If needed, i can send you the culprit mail in private.
