ignoring wayland, but won't start on qt.qpa, because could not find it

[dabzse]

generally I'm a Fedora "user", but I have to use Debian as well (not just because of the university)

this bug I found on the latest Debian, didn't try to install the package yet.

the "bug":
it didn't start, so I tried it from the terminal

$ ./Guitar-1.3.1-x86_64.AppImage
Warning: Ignoring WAYLAND_DISPLAY on Gnome. Use QT_QPA_PLATFORM=wayland to run on Wayland anyway.
qt.qpa.plugin: Could not find the Qt platform plugin "xcb" in ""
qt.qpa.plugin: Could not find the Qt platform plugin "wayland" in ""
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

zsh: IOT instruction (core dumped) ./Guitar-1.3.1-x86_64.AppImage

if you think this is not a bug, close the issue, and also extend the notification under AppImage

thank you
