IllegalArgumentException when merging multiple ways with conflicting tags and many relations

[Famlam]

What steps will reproduce the problem?

1. I merged a couple of ways (672544089, 672544091, 672544090, 6872773, 672983072, 672544089 and 672544088) in an attempt to simplify resolving the bus routes (i.e. moving to the new ways), prior to deleting these ways
2. Error

What is the expected result?

No error, conflict dialog opens telling me all kind of tags mismatch

What happens instead?

Error

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

Couldn't reproduce, unfortunately :(

In 18298/josm:

fix #20927 - ensure divider location remains between 0 and 1

@Vincent: Thanks, somehow this slipped my mind :(
