Description of problem: I opened cinnamon-menu-editor to manually add a shortcut for a newer FF-version to the start-menu, but as I clicked on the button "New Item" nothing happened. I therefor ran cinnamon-menu-editor in a terminal & saw this error as I reproduced this issue:

Traceback (most recent call last):
  File "/usr/bin/cinnamon-desktop-editor", line 5, in <module>
    os.execvp("/usr/lib/cinnamon-desktop-editor/cinnamon-desktop-editor.py", ("",) + tuple(sys.argv[1:]))
  File "/usr/lib64/python2.7/os.py", line 344, in execvp
