System.InvalidOperationException: Namespace prefix 'xsd' is not defined

Its bit strange error for me when i installed IE 10. After bit research i found this error can occur if you try to edit and save a list item entry in SharePoint. On non-development environments you see only this error message dialog (debug mode disabled):

 To solve this problem switch your browser to IE8 mode within the Internet Explorer Developer Tools: 

Now you should be able to edit and save the changes.
