18816	IAE at org.openstreetmap.josm.gui.history.HistoryBrowserModel	gaben	team	"==== What steps will reproduce the problem?
1. Edit something
2. Upload the changes
3. Open the edited object's history, then in the diff view click on the latest version

==== What is the expected result?
After changeset upload, JOSM should update the object versions as before.

==== What happens instead?
JOSM throwing exception

==== Please provide any additional information below. Attach a screenshot if possible.
Some time ago I noticed after uploading changes the diff tool sometimes became out of sync. I mean changes don't make a new entry in the history.
