Subject: emacs-guix segfault on searches with multiple package output results
From: Christopher Howard <[email-masked]>
To: Guix Bug Reports <[email-masked]>
Date: Sat, 09 Jan 2021 21:42:31 -0900
List-Id: <debbugs-submit.debbugs.gnu.org>

To reproduce:
- Start emacs
- M-x guix, p, n, gcc-toolchain

Also works searching instead for "mesa", another search that would have
multiple package output results.

Emacs crashes with a segfault:
