Segfault when using namespaces

[norro]

Mode manager raises a segfault when working with nodes that live in namespaces. The error happened when trying to prepend a namespace (e.g., in the example for one of the nodes) and prepending it to the node definition in the SMH file.

The problem is not directly related to namespaces. Namespaces not correctly declared for every instance of the particular part in the YAML file lead to a faulty vector access.
If namespaces are properly and consistently declared in the SMH yaml file, no segfault occurs.
