vineyard-preferences fails to start when not in debug mode

[Krzysztof Sikorski]

The latest revision (#268) fails to start when it's not in debug mode, and gives an exception in debug mode.

The normal launch ends with IndexError:

rad@reyka:~/vineyard$ ./vineyard-preferences
Traceback (most recent call last):
  File "./vineyard-preferences", line 687, in <module>
    if sys.argv[1] == '--create-profile':
IndexError: list index out of range

Debug launch shows an error, but the GUI appears and it seems to function normally (I tried browsing the options and running an app):

rad@reyka:~/vineyard$ ./vineyard-preferences --debug=debug
Traceback (most recent call last):
  File "./vineyard-preferences", line 407, in __configuration_changed
    wine.prefixes.use(selected)
  File "/home/rad/vineyard/python-wine/wine/prefixes.py", line 395, in use
    prefix_data = get_metadata_from_name_or_prefix(prefix_name_or_path)
  File "/home/rad/vineyard/python-wine/wine/prefixes.py", line 386, in get_metadata_from_name_or_prefix
    if prefix_name_or_path.startswith('/') and os.path.exists(prefix_name_or_path):
AttributeError: 'NoneType' object has no attribute 'startswith'

Thanks, I'll fix it. Things are a bit rough in trunk right now so expect breakage.

[Christian Dannie Storgaard (cybolic)]

Fixed in #269.

[Krzysztof Sikorski (krzysztof-sikorski)]

I pulled #269 and I there is no error in debug mode, but the IndexError still happen.
And now I realise these are two separate errors - the IndexError is not related to the debug mode, it happens whenever you launch vineyard-preferences without any command line parameters.

[Christian Dannie Storgaard (cybolic)]

Ah, not all files were included in #269, sorry.
#270 includes the changes.
