I think I found the problem. When we calculate what part of a merge
source (i.e. merge_source_t) to merge to a WC target we look at the
target's explicit or inherited mergeinfo and its history (e.g.
implicit mergeinfo) when deciding what has already been merged and
what remains to be merged. In most cases the implicit mergeinfo
covers a contiguous range, but in your example this is not the case:

Merge target 'branches\1.0':

Explicit or Inherited Mergeinfo:


Implicit Mergeinfo:


It's that gap in the mergeinfo for trunk that is causing the problem.
We are trying to merge it, which causes the error you see. We should
be ignoring it.

Working on a fix right now.
