I don't think it only crashes when there is an attachment. It seems to crash irrespective of whether there is an attachment, but usually after I attempt to send an email, with the following output on the console:
EI: MAIL PREFSSegmentation fault -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/686404 Title: evolution crash after send an attachment -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
