Thanks for confirming. Strangely, I was now able to reproduce the crash with your recipe on nano-2.4.2. I think it has been fixed since then by commit 8a06dfa on August 2 last year, which was a fix for a Debian bug [1], which went into 2.4.3 and later.

I don't use Ubuntu's package; I only run nano built from source.
