Please CC <newpackage>@packages.debian.org when you reassign a bug, all
I received was the message from the control bot, and I had to look up
the report on the Web.

It goes without saying that all these programs work fine on ten
thousands systems, so I suspect this is a problem on your site. Please
run "debsums libncursesw5 ncurses-base" and fsck your filesystems.

Unfortunately strace is useless for segfaults. Please install
libncursesw5-dbg and run the program under GDB, e.g.
LD_LIBRARY_PATH=/usr/lib/debug gdb nano
When the program segfaults, type "bt" at the gdb prompt and send the
backtrace. Hopefully gdb does not segfault itself 8-) (it's linked
against libncurses5, but not libncursesw5).
