I've been experimenting with notmuch, and at some point, I started getting this panic:

panic: runtime error: invalid memory address or nil pointer dereference

My querymap file is:

inbox=tag:inbox and not tag:archived

And my relevant configuration for the notmuch source is:

source   = notmuch://~/mail
query-map = /home/alex/.config/aerc/querymap
outgoing = smtps+plain:<redacted>
default  = INBOX
from     = alex wennerberg <alex@alexwennerberg.com>
copy-to  = Sent

Tried some dumb solutions: restart my machine, reinstall aerc. Unsure what led to this state -- it was working fine before and the only thing I changed that I'm aware of was modifying the querymap file, but I've restored the config to the state it was before and I'm still getting this panic. The error only occurs when the notmuch section is configured -- if I comment it out and leave the IMAP configuration for the same email address, there is no issue.
