-- Information about the crash:
I ran into this crash when I got a bunch of invitations (after setting up a
Matrix bridge) and clicked through each notification accepting or rejecting it.
The stack trace suggests that I rejected this one, and I remember that I did
reject an invitation shortly before it crashed, so I'm willing to believe it.
While processing the rest of the invitations after restarting NeoChat, I
couldn't reproduce the crash or figure out what the exact conditions are for
it. Accepting and rejecting other invitations from the notifications worked
fine.
NeoChat is compiled from git commit 39388e204ede5d8b8a570c12258207901d12abfb.
It may or may not be useful, but the id for m_lastCurrentRoom looks suspicious
if it's not only related to the warning:
