           Summary: Segfault on reply
           Product: Claws Mail
           Version: 3.7.9
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P3
         Component: Other
        AssignedTo: users at lists.claws-mail.org
        ReportedBy: clawsmail at lerneaenhydra.net


I've encountered an unexpected issue that causes claws-mail to segfault. So far
I've determined that I can cause claws-mail to crash by pressing the reply
button for a few emails sent by a specific person (this is completely
repeatable). So far it seems like there needs to be an attachment to cause the
crash. There's nothing very seemingly strange with the message and it was sent
by someone I trust so there's no risk of an intentionally malicious user. The
message was sent from microsoft's outlook.com portal, connected to their
live at edu system. A later message I recieved (without an attachment) does not
cause claws to crash. Below is the gdb output, both when selecting the email
(which doesn't cause any perceptable error) and when clicking the reply button
which instantly causes a segfault.
