libdecor_decorate() already creates an xdg_surface and xdg_toplevel
internally for the frame. Calling xdg_surface_get_toplevel() again on
that same xdg_surface just to fetch the toplevel for icon handling
assigns the xdg_toplevel role to the underlying wl_surface a second
time, which is a protocol violation.
On GNOME Shell 50 (mutter) this is no longer tolerated: mutter
terminates the Wayland connection ("WL: error in client
communication"), and since libdecor_shellInit() waits for the initial
configure with a blocking, error-less libdecor_dispatch(-1) loop, the
client hangs forever with no window and no diagnostic output. This
made -DENABLE_LIBDECOR=ON (the default when libdecor-0 is present)
appear completely broken on current GNOME/Wayland.
Use libdecor_frame_get_xdg_toplevel() instead, which returns the
xdg_toplevel libdecor already owns, without requesting a second role
assignment.
Require libdecor-0 >= 0.1.1, which is available in Debian oldstable,
so the new accessor is guaranteed by the build dependency.
