[Python-apps-team] Bug#974144: Fails under wayland and fails trying to select a window

Package: kazam
Version: 1.4.5-4
Severity: grave

I tried kazam. First the errors shown on the command line clearly indicate that
it is not supposed to work with wayland:

(kazam:89108): Wnck-WARNING **: 16:47:15.482: libwnck is designed to work in X11 only, no valid display found
Traceback (most recent call last):
  File "/usr/lib/python3/dist-packages/kazam/frontend/window_select.py", line 111, in cb_button_press_event
    screen.force_update()
AttributeError: 'NoneType' object has no attribute 'force_update'

This can be fixed by calling the program with the X11 backend set:

$ GDK_BACKEND=x11 kazam

(JFTR: If either libwnck or kazam is designed to work with x11 only it should
call gdk_set_allowed_backends() at some point).

But even after setting the backend it is impossible to choose a window:

Traceback (most recent call last):
  File "/usr/lib/python3/dist-packages/kazam/frontend/window_select.py", line 116, in cb_button_press_event
    if win.is_visible_on_workspace(workspace) and win.is_in_viewport(workspace):
TypeError: Argument 1 does not allow None as a value

The program actually looks pretty dysfunctional for me at this point. I don't
think this should be shipped with the next stable.

Regards, Daniel
