I have found that this is caused by adding the entries from a heat extraction
of a COM library as well as some extra-manual RegistryValue elements for the
interfaces under HKCR.
Example causing the exception:

</Component>
To fix it simply put in your component only what heat.exe generates. I
would put business-logic specific registry entries in another component and
fragment.
