steps to reproduce:

  1. add new contact
  2. before key exchange completes, rename contact
  3. after key exchange completes, send a message
  4. the above crash occurs
  5. after relaunching and trying to message them again: the same crash happens again.

note: i have not actually tried to reproduce this yet, but the above are the series of steps i took when it happened once.

update: after receiving a message from the contact, i was able to message them without triggering a crash.

the rename of contact assigned a map entry for the nickname to nil
