NPE pasting tags with different values

[skyper]

What steps will reproduce the problem?

1. select to ways with slightly different tags.
2. copy tags into buffer {Ctrl+C)
3. select different way and past tags {Ctrl+Shift+V)

What is the expected result?

Tags should be pasted and all values should be added with semi-colon separated.
At leat a warning but no NPE.

What happens instead?

Exception

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

I attach the osm. I wanted to copy from the two track onto the path.
