Reproducible: Sometimes

Steps to Reproduce:
1. scr components may trigger it
2. felix webconsole components page shows exception
3. component still seems to work; the component registers a service as seen from the felix webconsole services page

to clarify, component DS/SCR registration seems to work; still have to really test if it actually does.

Proposed patch for the problem

This problem can happen when browsing disabled components which do not have any properties.
This problem does not affect the work of SCR or the components. It may affect only the users of service org.apache.felix.scr.ScrService.

Tom, can we consider fixing this also in 3.7.1?

Stoyan, please release to head for Juno.  Patch looks good.  I will create a cloned bug for 3.7.1.
