* src/ls.c (gobble_file): Work around a bug in libselinux1-2.0.15
whereby getfilecon returns 0 yet sets the context to NULL.
Reported by Jan Moringen via Michael Stone in
http://bugs.debian.org/463043
* tests/ls/Makefile.am (TESTS): Add proc-selinux-segfault.
* tests/ls/proc-selinux-segfault: Test for the above fix.
* NEWS: Mention the fix.
