There is an old bug that when doing too many changes in kmenuedit, the app just crashes. Not nice, probably some oom or whatever (I am not a programmer haha)
Dolphin recently crashes too, silently in the background.
I have “gdb” installed on Fedora Kinoite, to be able to report bugs. But when running
gdb (gdb) run dolphin # or (gdb) run kmenuedit
I always get
Starting program: dolphin No executable file specified. Use the "file" or "exec-file" command.
