Inconsistent JOSM state when resolving conflicts leads to internal error

[avarab@…]

What steps will reproduce the problem?

1. Edit an area
2. Get conflicts
3. Solve some of them
4. Selectively upload data with "upload selection"
5. Upload actually works
6. Conflicts remain even though I have nothing to upload when I try
7. Click on one of the unsolved conflicts which evidently don't exist
8. Get this backtrace
