Hey, on bullseye, with dbus-x11 installed, same bug with gdebi-gtk about crashing whenever I click "install". Crash and in the loggs I can read "refusing to render service to dead parents."
The workaround I found for now is just "wrapping" debus-gtk in a shell (as I discovered that launching gdebi-gtk from a terminal emulator worked). That launcher work : Exec=sh -c "gdebi-gtk %f" Why ? I have no clue.
