the Plugin "tagging-preset-tester" produce an error message

[tijuca]

To prevent any side effects by other plugins I create a new local enviroment by deleting the folder ~/.josm in my $HOME so I get a clean new standard setting from JOSM.

I just installed the plugins restart and the tagging-preset-tester.

I load a own created preset, based on the preset from ​http://www.asamnet.de/~fischept/osm/oepnv_preset.xml.

Now I download a small part of OSM data. After this i press the buttons "Alt+Shift+A". Shortly appears the error message.
I tried also the Shortcut without an OSM data or *.osm local loaded, the error is the same.
