-- Information about the crash:
I tried to update a 1:1 chat from version 6 to 12 (using NeoChat). It worked
only half-way, because NeoChat crashed and I had to manually invite the other
user to the newly created room. In Element, it looks now good and as expected:
One room with the possibility to go to the old room. In NeoChat, both the old
and the new room appear in the room list. And NeoChat keeps crashing if I
select one of them.

The crash can be reproduced every time.
