[Tails-testers] IceDove crashes on send.

IceDove email program crashes when sending mail. Not every time, but
often enough to prove frustrating. When a crash occurs email is not
sent and does not appear in the sent folder. There may or may not be a
partially composed email in the drafts folder depending on how long it
took to type the message. I am now testing 3.0 alpha1 but have
experienced this issue with earlier versions too.

I have used Thunderbird for years, both with and without going through
Torbirdy, and have not had this problem with any distro but Tails.
