[Users] Crash in mailstream_close at mailstream.c:300 once more

[Michael Schwendt]

Hello, everyone!

Any idea what issues related to interrupting IMAP access are still
present?

The following from the backtrace at
  https://bugzilla.redhat.com/attachment.cgi?id=1118186
is about 3.13.1 and has been hit before in 3.11.1 (2014).

If memory serves correctly, mailstream.c is libetpan, which is 1.6
here. Likely it's a NULL-ptr crash.

Any ideas?

Hmmm ... while writing this and a reply in bugzilla, a brief
search turnt up this:
http://lists.claws-mail.org/pipermail/users/2015-March/012457.html

Guidance highly appreciated. Please.
