    Workaround for EXIF data import which crashes the plug-in.
    
    This workaround allows to run the plug-in when opening a JPEG. The
    import/merge of EXIF data is currently not working. All data is set as a
    scalar property. This is invalid data by the XMP metadata
    standard.  A proper fix will need more code for the import in
    exif-decode.c
