Error when pressing [ENTER] in an empty list

[Gernot]

when pressing the enter key in an empty list or list_preview you get an Error:
IndexError: list index out of range

Traceback (most recent call last):
  File "C:\elisa_win32\upicek_network\elisa-plugins\elisa\plugins\pigment\widgets\list.py", line 546, in do_clicked
    item_clicked = self.model[index_clicked]
IndexError: list index out of range

[Florian Boucault (fboucault)]

The bug described does not match with the traceback. That is the real traceback:

Traceback (most recent call last):
  File "/home/kaleo/dev/elisa/upicek/elisa-plugins/elisa/plugins/pigment/pigment_frontend.py", line 396, in handle_input
    self.controller.handle_input(input_manager, input_event)
  File "/home/kaleo/dev/elisa/upicek/elisa-plugins/elisa/plugins/poblesec/main.py", line 170, in handle_input
    if self.focused_controller.handle_input(manager, input_event) == True:
  File "/home/kaleo/dev/elisa/upicek/elisa-plugins/elisa/plugins/poblesec/poblesec_browser_controller.py", line 597, in handle_input
    self.history.current.handle_input(manager, input_event) == True:

    item = self.nodes.model[self.nodes.selected_item_index]
IndexError: list index out of range

The traceback in the description is a real one though and now fixed.
