Dataset consistency failure on Join overlapping Areas

[Ldp]

• Open the attached .osm file.
• Select both areas and invoke Join overlapping Ways.
• "No intersection found. Nothing was changed." Click OK.
• Merge top left and bottom right nodes, so you get 2 adjoining areas.
• Select both areas again and invoke Join overlapping Ways.
• "An unexpected exception occured. This is always a coding error." Acknowledge the popup.
• The merged nodes are now slightly separate again, but not in the original positions.
• Every further attempt to Join overlapping Areas gives the bug popup.

Saving out to .osm after the exception results in an inconsistent file as well. Properly undoing before saving seems to help.
