KVIrc instantly crashes and can't startup on Wayland session

[MirceaKitsune]

I recently noticed that KVirc will no longer start up when using a Wayland session. It works perfectly fine in X11 but if I choose Wayland it refuses to run. No detail is provided if starting up from a console, just the typical "segmentation fault" which is a fancier keyword for "it crashed". As I don't run from Git and using gdb is complex I hope others can easily reproduce this.

My OS is Manjaro and my DE is KDE, this issue happens with the Wayland session for Plasma. KVIrc is installed from the distro's system packages. Note that to test Wayland on KDE you need to install the package plasma-wayland-session in Manjaro. I haven't tried reproducing it in a VM but hopefully it works there too which should make testing easy. This is the system info from the about section, X11 session which I'm still using by default until Wayland is more stable.

I'm still getting the crash on Plasma 5.25.3 on Manjaro. Is there any news on this please? If the issue can't be addressed I'll likely have to switch to a new IRC client once everything else allows moving to Wayland.

No one stepped up because nobody could reproduce your problem. I'm afraid news on your issue can only come from you atm.

Sorry for the delay. I set up a VM to test the issue: It appears the latest Git version doesn't produce this crash, KVIrc will start fine on Plasma Wayland session. Either it's related to how the package is compiled, or most likely it was fixed in a later commit.

Does anyone know when a new KVIrc release may take place? Would it be possible to update the Manjaro package? I'll ask on the Manjaro forum as well to see about this, but possibly let me know who manages the repos and if they can help.

The kvirc 5.0.0 version shipped with Fedora 37 has an instant crash when running under Wayland. I will try building the latest Git version to see if it runs.

I wonder if there's output when you run kvirc in terminal

I've build KVirc from current mster https://github.com/kvirc/KVIrc/commit/681f0940b6499d83b35bbfea2695aaedb34726e2 And no crashes under wayland.
