    combo-layer: fix crashes on wrong tempfile usage
    
    When calling tempfile.NamedTemporaryFile().write(str()), at least on
    Python 3.4.2 this fails with this error:
    TypeError: 'str' does not support the buffer interface
    
    Change the file-mode for all such files from binary to text mode.
