show visual message for OSError from importing vineyard in vineyard-preferences

[Krzysztof Sikorski]

This is more a feature request than a bug report.

When the ~/.wine directory is missing, importing vineyard module fails with rather obvious OSError:

Traceback (most recent call last):
  File "/usr/bin/vineyard-preferences", line 26, in <module>
    import vineyard
  File "/usr/lib/pymodules/python2.6/vineyard/__init__.py", line 9, in <module>
    from common import *
  File "/usr/lib/pymodules/python2.6/vineyard/common.py", line 146, in <module>
    import wine
  File "/usr/lib/pymodules/python2.6/wine/__init__.py", line 62, in <module>
    prefixes.use(prefixes.get_name(common.ENV['WINEPREFIX']))
  File "/usr/lib/pymodules/python2.6/wine/prefixes.py", line 162, in use
    drives.auto_mount_images()
  File "/usr/lib/pymodules/python2.6/wine/drives.py", line 154, in auto_mount_images
    for drive in os.listdir('%s/dosdevices' % common.ENV['WINEPREFIX']):
OSError: [Errno 2] No such file or directory: '/home/rad/.wine/dosdevices'

I suppose this is desired behaviour, but this error is not caught in vineyard-preferences which makes it fail silently on start with no visual clue to the user, only a traceback in the console. Maybe a message box with short info (f.ex. "you should run winecfg first") would be better?

Actually no, it's not desired behaviour, so thanks for reporting it.

python-wine will now create the ~/.wine directory and configuration if it's missing.
