[Pkg-gnupg-maint] Bug#773473: [PATCH] * sm/gpgsm.c: (parse_keyserver_line) return false on 'fail'.

[Joshua Rogers]

--

If something in the keyserver_line failed, parse_keyserver_line would free 'server', but then return it afterwards, leading to a use-after-free.

sm/gpgsm.c, in the function main() correctly checks whether the return of parse_keyserver_line is false.
