Description of problem:
After selecting a text file (Document/plain text) from a directory, the
right-click menu fails to execute any applications associated with mime file
type. Furthermore, if the user selects "Other Application" from the menu,
nothing happens.  

However, the right-click menu appears to work for all other types of files
(.doc, .jpg, etc). 

Presently, the only way this newly-installed software will load a text file into
an application is to double-click on the text file to load it into the Nautilus
viewer and then select an application (i.e. gedit) that appears in the side-pane.
