NPE during download

[skyper]

What steps will reproduce the problem?

1. start JOSM
2. download some data
3. download some more data

What is the expected result?

Download finishes without NPE

What happens instead?

Download Progress Bar appears and NPE

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

I did only download some objects and the download did work. Maybe it did finish too fast. I did notice that a lot of windows do open in to small windows (progress bar, conflict manager, relation editor).

Gnome3 with metacity
