Overriding a hst:component with a hst:containercomponent fails

Please take a look at the attached stacktrace.

So what I have:

componentsA
` base (hst:component)
` content (hst:component)

componentsB
` extended (hst:components)
+ hst:inheretsfrom = ../../componentsA/base
` content (hst:containercomponent)
