crash on git-fast-import

[Rob Herring <robh@kernel.org>]

Hi,

lei started crashing on me today in git-fast-import. Nothing changed
on my system that I'm aware of. At first, I thought something stale
was lingering after my GNOME session died yesterday. I've since
rebooted and wiped out ~/.local/share/lei/store, but the issue
remains. I'm running commit e7c8ab553ee2 ("eml: reuse ->decode
buffer").

Here's an example:

$ lei up ~/Mail/from-me/
# https://lore.kernel.org/all/ limiting to 2024-01-21 16:33 -0600 and newer
# /home/rob/.local/share/lei/store 0/0
# /usr/bin/curl -gSf -s -d ''
https://lore.kernel.org/all/?x=m&t=1&q=(dt%3A20240206145113..+AND+(f%3Arobh%40kernel.org+OR+f%3Arobh%2Bdt%40kernel.org)+AND+NOT+(nq%3AAcked-by+OR+nq%3AReviewed-by))+AND+dt%3A20240121223337..
fatal: Expected committer but didn't get one

If the output is json, it works:

$ lei q -I https://lore.kernel.org/all/ 'f:robh d:1.day.ago..' > /dev/null
# /usr/bin/curl -gSf -s -d ''
https://lore.kernel.org/all/?x=m&q=f%3Arobh+dt%3A20240305154252..


Any ideas or tips for debugging this?
