The patch works! Got a little confused by caching of the paths, which was returning /usr/local/bin/nano, but without the qualified path, it was using /bin/nano. Easily fixed What happens next? I noticed your thread over at https://lists.gnu.org/archive/html/nano-devel/2015-11/msg0.html - I guess a patch to their svn, and then something related in debian/ubuntu repo? Then poking someone to get a new package built and distributed?

[Touch-packages] [Bug 1509081] Re: nano segfaults as root after upgrade to 15.10
Yup, 15.10 seems to. I have never edited the /etc/nanorc file, so I guess it was just updated to the default package maintainers version as per the usual. So the grep gives the obvious output: reedy@ko-kra:~$ grep locking /etc/nanorc set locking reedy@ko-kra:~$ Yeah, I ended up applying the patch by hand. I guess debugging tired (on unfamiliar source code). I should have really noticed what the issue was! Will try the patch again on the source from the 15.10 apt repo Will post the ./configure stuff to nano-devel; that's fine by me.
