    Sort columns of process selection dialog displays warning (Closes: #534700)
    
    	* src/persp/dbgperspective/nmv-proc-list-dialog.cc: This seems rather hacky,
    	  but I believe it's the 'proper' way to do it in GTK+: wrap the base
    	  ListStore in a TreeModelFilter (which provides filtering capability but
    	  removes sorting capability), and then wrap the TreeModelFilter in a
    	  TreeModelSort, which adds sorting capability back...
