Qt5/6 Settings crashes, if I switch to the “Fonts” tab and click the “…” button to select a font. There is this old post that asked about the same thing. The marked solution was setting
export QT_QPA_PLATFORMTHEME='gnome' in the zshrc, but that did not work. It only worked when I executed
export QT_QPA_PLATFORMTHEME='gnome' in the terminal and then run it with
qt5ct. But it showed that the configuration is not correct warning panel at the top.
After some trying, I have found that I can make it not crash by changing the “Standard dialogues” value from “GTK3” to “Default” (and restart the configuration tool).
But why does the tool crash if the dialogue is set to GTK3"? Is this a bug or because some component is missing? In either case, shouldn’t this be fixed?
