Null Pointer Exception when trying to resolve conflicts

[smsm1]

When in the resolve dialog, there is nothing to choose from, so get an exception, and can't actually resolve the conflicts. This happens when there are conflicts with ways, relations. However I'm yet to come across it with nodes.

[Hasienda]

this ticked has a better error message wording with regard to debugging, however it's essentially a duplicate of #1568, that in turn was marked as a duplicate of # 1405 itself

I'll update that oldest ticket with the additional information found here.
