IAE: Listener improveway.ImproveWayAccuracyAction was already registered

[skyper]

I have several problems but it seems to me that the extantion of the class does not work properly

What steps will reproduce the problem?

1. try to activate mode for the first time

What is the expected result?

working mode

What happens instead?

IllegalArgumentException

Please provide any additional information below. Attach a screenshot if possible.

The first three times JOSM did completely crash after downloading osm data. I have twice the same mode button (one for function from core and another one for the plugin function)
