Random(?) crash after accepting invite #1122

Open tastytea opened 2 years ago

tastytea commented 2 years ago

Describe the bug

Immediately after i accepted an invite to a space, nheko crashed. I could not reproduce it with the same space, another space or a “normal” room. But i have a backtrace. 😊

To Reproduce

  1. invite an account to a space
  2. accept invite
  3. crash (maybe)

What happened?

I had 2 instances of nheko open, with different profiles. From instance 1 i invited the account in instance 2 to the space #stickers-and-emojis:pixie.town. Then nheko crashed.

Expected behavior
