Comment 13 for bug 560591

I think you got this bug because you have more than one language listed in the locale. So, to fix it, please follow these steps:-

1- go to the start menu and click on the System settings
2- from the pup up window click on Locale
3- Look at the Preferred Languages: section of the window
4- if there is a language other than English or your preferred language, just move it to the Available Languages: by highlighting it
and clicking on the left arrow.

That should fix the problem
