5067	Latest JOSM crashed while uploading	anonymous	anonymous	"What steps will reproduce the problem?
 1. Do some changes
 2. Upload the changes
 3. See the crash.
I uploaded a few changesets without a problem, so it does not crash every time.

What is the expected result?
Uploading the changes without problems.

What happens instead?
Crash

I started JOSM from commandline because I wanted to see what's going on, because the API is so damn slow at the moment. I'll attach the last lines. The numbers in the first line are from a download and are not relevant.
