Subject: [PATCH] mandb: Fix crash when processing stray cats

Regression introduced in man-db 2.11.0.  Fixes Debian bug #1027487.

* src/straycats.c (check_for_stray): Pass a basic trace list to
`store_descriptions`, since that's required as of commit
d3e4b5522ae8152f10db0bb98e6873c9cc17ed59.
* NEWS.md: Document this.
