There seems to not be a strict rule to only have armatures as parents to single bones, apparently collada files can also be set up to have mesh parents for bones. As a consequence, the collada importer `joint_parent_map` is not safe to fetch objects from and assume their data can be cast to `bArmature`. Ultimately, the `joint_parent_map` needs to be looked at again, this patch just avoids a crash in this scenario (so no such joints will be iported). Still better than crashing I guess.
