Dear Maintainer,
on a fresh debian 13 install (default gnome desktop), doomsday segfaults on
start with the following error message:
***
QSocketNotifier: Can only be used with threads started with QThread
Segmentation fault
***
thanks,

Hello,
this crash seems related to using a Wayland desktop.
I get a backtrace as shown in [2] using a Plasma Wayland session.
As a workaround, please check if starting doomsday
with this command line avoids the crash:
QT_QPA_PLATFORM=xcb doomsday
Using this environment should make Qt use the XWayland server,
and is mentioned in the upstream forum [1].
Because this shouldn't "rendering it completely unusable to everyone",
would severity important be better suited?
Kind regards,
Bernhard
