      Trivial to reproduce, just set a field to a string, then try to multiply it and you get the $inc error:

      db.foo.update({}, {$mul : {a : 2}}, false, {multi : true}, {ordered : false})
Update WriteResult({
	"ok" : 1,
	"nDocsModified" : 0,
	"n" : 0,
	"writeErrors" : [
		{
			"index" : 0,
			"code" : 16837,
			"errmsg" : "Cannot apply $inc to a value of non-numeric type. {_id: ObjectId('52d44e8d4166d7524db9bd2d')} has the field 'a' of non-numeric type String"
		}
	]
})

      Proposed fix (needs validation):
