Short description of error

The python call to bmesh.ops.weld_verts allways raise the following error:
NotImplementedError: weld_verts: keyword "targetmap" type 10 not working yet!
even using bmesh.ops.find_doubles which returns the targetmap needed by the function.

Exact steps for others to reproduce the error

Code to run to reproduce error :

import bpy
import bmesh

bm = bmesh.new()

# creates a new cube with size 1
bmesh.ops.create_cube(bm)

# try to merge some verts
verts_to_merge = bm.verts[0:4]
verts_to_keep = bm.verts[0:2]
ret = bmesh.ops.find_doubles(bm, verts=verts_to_merge, keep_verts=verts_to_keep, dist=2.0)

- ret= {'targetmap': {<BMVert(0x725a130), index=2>: <BMVert(0x725a0c0), index=0>, <BMVert(0x725a168), index=3>: <BMVert(0x725a0c0), index=0>}}
- Raise : 'NotImplementedError: weld_verts: keyword "targetmap" type 10 not working yet!'
bmesh.ops.weld_verts(bm, targetmap=ret['targetmap'])

me = bpy.data.meshes.new("Mesh")
bm.to_mesh(me)
bm.free()

scene = bpy.context.scene
obj = bpy.data.objects.new("Object", me)
scene.objects.link(obj)

scene.objects.active = obj
obj.select = True

Further investigation

I think the error is in /blender/source/blender/python/bmesh/bmesh_py_ops_call.c
In method bpy_slot_from_py, the type 10 (BMO_OP_SLOT_MAPPING) exists, but due to a missing break keyword (line 509 I think), we fall in the default code which prints the message and returns -1
