Bug#940671: alacarte crashes on start with GNOME 3.34 installed

[Matteo Settenvini]

Package: alacarte
Version: 3.11.91-5
Severity: important

Dear Maintainer,

whenever I attempt to start alacarte with GNOME 3.34 installed,
I get the following output:

$ alacarte
/usr/share/alacarte/Alacarte/MainWindow.py:22: PyGIWarning: GMenu was imported without specifying a version first. Use gi.require_version('GMenu', '3.0') before import to ensure that the right version gets loaded.
  from gi.repository import Gtk, GdkPixbuf, Gdk, GMenu

(alacarte:10516): Gtk-WARNING **: 21:44:38.368: Theme parsing error: gtk.css:6:20: The 'gtk-key-bindings' property has been renamed to '-gtk-key-bindings'

  File "/usr/share/alacarte/Alacarte/MainWindow.py", line 62, in setMenuBasename
    self.editor = MenuEditor(menu_basename)
  File "/usr/share/alacarte/Alacarte/MenuEditor.py", line 36, in __init__
    self.load()
  File "/usr/share/alacarte/Alacarte/MenuEditor.py", line 49, in load
    if not self.tree.load_sync():
gi.repository.GLib.Error: g-markup-error-quark: Errore alla riga 1 carattere 1: Il documento era vuoto oppure conteneva unicamente spazi (1)


The program then exits.

Cheers,
Matteo Settenvini
