Bug#722611: mutt: segfaults when sending with SMTP

[Ondřej Surý]

Matteo,

I did miss this bugreport since it doesn't notify the new maintainer
when the bug is reassigned.

Did you or could you please report this to the upstream bugzilla? I have
a little free time right now, so that would be very helpful.

Cheers,
Ondrej
