Hi, This might not be the right place to report this but I've just discovered that the mutt package on debian9 stable (or rather NeoMutt 20170113 (1.7.2)) segfaults if you ask it to write to a readonly mbox file. It happened several times yesterday before I realised what was wrong (and yes, I did have a reason for wanting some mbox files to be temporarily read-only).
touch readonly chmod 400 readonly mutt Save any message to the readonly mbox and... /home/raf/mail/readonly: Permission denied (errno = 13)[1] 25270 segmentation fault mutt Happens every time (for me). So don't do that. I know it's an old version and it might have been fixed (but I couldn't see that it has from the changelogs). But if you use debian9 stable, this is the version you'd get. If I can get past neomutt's configure script, I'll see if it's still a problem. It seems that it can't find libncursesw no matter how many ways I tell it where it is. cheers, raf
