Hi all,

I plan to commit the attached patch as obvious, unless anyone objects.
It fixes another case of class container naming collisions (comment
#12/#19 in the PR). We had fixed a few such cases before, and I hope
there are not much more left ...

I am in the process of regtesting and will commit tomorrow if no one
objects until then.

Cheers,
Janus
