Nor can I. I think this bug can be marked as done.

Best wishes,

Hi,
do you mind checking against the latest version (1.7.1-5)? I believe all pager
bugs have been fixed and I've also pulled out a patch which might be related

I can reproduce Hannes's bug. It doesn't happen to me every time, but it
happens with an annoying frequency. It also happens after running ispell
on a message. Frequently, the message in the bottom status line at
segfault time is "Fetching headers...".

I've attached two backtraces of the segfault, which look identical
modulo some irrelevant details like account names and FCC.

Please let me know if there's any further debugging information you can
use.

Best wishes,
Ryan

Bug#842062: mutt segfaults when leaving pager view of composed message on new message

[Hannes von Haugwitz]

Package: mutt
Version: 1.7.1-2
Severity: important

Hi,

mutt 1.7.1-2 segfaults when leaving pager view of composed message on new
message:

Reading /var/mail/hvhaugwitz... 0Segmentation fault

Steps to reproduce (on up to date sid):

- install postfix (local only config), mutt and bsd-mailx

- run mutt as user hvhaugwitz (without config)

- compose mail and open composed message in pager

- $ echo Test | mail -s "Test" hvhaugwitz

- leave pager by pressing 'i' or 'q'

Best regards

Hannes
