[Bug 1619801] [NEW] upstart-monitor does not work in no-gui mode if Gtk is not available

[Stuart Langridge]

Public bug reported:

upstart-monitor attempts to detect if graphical modules are not
available and run in no-gui mode (and this can also be explicitly
specified on the command line). However, if the modules are not
available, Python fails to parse the code because something inherits
from Gtk.Window even though Gtk is not available.

# upstart-monitor --no-gui
WARNING: GUI modules not available - falling back to CLI
Traceback (most recent call last):
