In older SharePoint versions this column was linked to the document. Since SharePoint 2010 this has been removed but unfortunately not the description for the column.
The Icon will still be shown as before but the click on the Icon will not open the file anymore. This behavior with SharePoint 2010 is by design. Removing the wrong text in the description is addressed for all the languages we offer for SharePoint 2010.
I found the following KB article and it explained a way how to get that functionality back.
