I think I am affected by the same bug (not sure tho).
Every time I suspend my laptop and resume on a different internet
connection mutt crashes. Its easily reproducible (at least on my end)
I used gdb to get a backtrace. -d 2 does not seem to do anything?
Attached are both a backtrace and a full backtrace
Starting program: /usr/bin/mutt -d 2
[Thread debugging using libthread_db enabled]
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
Program received signal SIGPIPE, Broken pipe.
