Okay.  Does it also occur when you use 'nano --ignore'?
(Or rename your nanorc files to something else?)

If not, please find the configuration option that triggers it.

If yes, can you build from git?  If so, then please bisect --
21469422 should be good, and 08b770d4 should be bad.

It seems to be lockfile-related.  So commenting out the
'set locking' line in /etc/nanorc will probably avoid the
problem.
