Bug 506764

Application: neochat (25.04.3)

ApplicationNotResponding [ANR]: false
Qt Version: 6.9.1
Frameworks Version: 6.15.0
Operating System: Linux 6.15.4-200.fc42.x86_64 x86_64
Windowing System: Wayland
Distribution: "Fedora Linux 42 (KDE Plasma Desktop Edition)"
DrKonqi: 6.4.2 [CoredumpBackend]

-- Information about the crash:
Note that this might be a bit of a particular situation to the fedora homeserver.

We have a bit of an issue where, if someone links some of our channels to someone else, that someone else cannot join the channel with Element, gives an "M_UNKNOWN" error.

So I figured, "Might as well try to see what I get with Neochat, just for fun!"

At first, clicking the link did nothing, then after roughly a minute, the app crashed. And now, it seems to crash everytime I open it.

I figured this crash might be caused by an "unhandled exception", so I thought submitting it as a bug might still be useful for you guys.

The crash can be reproduced every time.
