Pre-Process File Save As does not work

On xubuntu-18.04-desktop-amd64.iso using Inkscape-beb7fdf-x86_64.AppImage

Running

Extensions > Export > Pre-Process File Save As... > Apply

with an empty document and nothing selected results in

Traceback (most recent call last):
  File "prepare_file_save_as.py", line 56, in <module>
    PrepareFileSave().run()
  File "/tmp/.mount_InkscahBdORb/usr/share/inkscape/extensions/inkex/base.py", line 84, in run
    ret = self.effect()
  File "prepare_file_save_as.py", line 44, in effect
    file = self.args[-1]
AttributeError: 'PrepareFileSave' object has no attribute 'args'

Please note: I only tested this on the system described above; I cannot guarantee that the same error exists in non-AppImage versions. Please let me know if it does not, so that we can iron out any remaining issues concerning bundling a private copy of Python inside the AppImage.
