bug#59676: 30.0.50; package-report-bug fails getting maintainer address

[Eshel Yaron via "Bug reports for GNU Emacs, the Swiss army knife of text editors" <bug-gnu-emacs@gnu.org>]

1. emacs -Q
2. M-x list-packages
3. Move point to over some package, e.g. Magit
4. M-x package-report-bug
5. See error:

package-maintainers: Wrong type argument: char-or-string-p, ("Jonas Bernoulli" . "jonas@bernoul.li")

On another note, seems package-report-bug could also benefit from an
autoload cookie, no?


Thanks!
