"an unexpected error has occured"

[mrgenie]

What steps will reproduce the problem?

1. dunno - just working the same as I always do - didn't get this before

What is the expected result?

I just clicked the commit changes button - that's it.

What happens instead?

Nothing - got this "you have encountered a bug in JOSM"

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

I honestly have no idea - since I don't see anything going wrong other than this popup telling me about an unexpected error - not sure if it committed my changes or if all the work is lost now.. who knows.

Ah no - commit went through properly - so I have no idea what's actually wrong - nothing seems to be wrong just got this message that's it..
