Comment 26 for bug 772549

I am experiencing this bug also - with the blank window up I did the following in a terminal:

dgodec@Dimension-4600:/usr/share/themes/Orta$ killall software-center
dgodec@Dimension-4600:/usr/share/themes/Orta$ software-center
2011-07-26 03:59:33,961 - softwarecenter.fixme - WARNING - logs to the root logger: '('/usr/share/software-center/softwarecenter/view/widgets/mkit_themes.py', 675, 'retrieve')'

The workaround solved it temporarily - I will continue to run the app via terminal so I can post output when it is re-created.
