Tor crashes if ClientOnionAuthDir contains more than one private key for a hidden service

OS: Arch Linux,

Minimum torrc to reproduce problem:

ClientOnionAuthDir /var/lib/tor/auth

In /var/lib/tor/auth place a file, for example "key1.auth_private" with:

squlj76moawedtuiixydwlzj65323e6k232bpogd4xrrsz4bgcunyqad:descriptor:x25519:XX5M5YQVTGCXPS3E6G6AGOUZYFISOLMSXLD2E3BTL22DUQZLHK4Q

then do

# cp /var/lib/tor/auth/key1.auth_private /var/lib/tor/auth/key2.auth_private
# tor -f /etc/tor/torrc

This yields the traceback:
