segfaults on calls on Debian 12

[anarcat]

FluffyChat completely crashes when I try to make a call on Linux (Debian 12 "bookworm"):

Feb 08 14:02:00 angela dmenu-bash-history[1579924]: Warning: Failed to respond to a message. This is a memory leak.

This happens right after I click the "voice call" after clicking the phone icon.
