...after abd630e81b "Allow all hierarchical path
segments to be ['...'] quoted", which failed as the checked
MimeTypeClassIDRelations group is conditional on install:module="reportbuilder".

"Allow all hierarchical path segments to be ['...'] quoted".)
It looks like there is no other, non-conditional property with a slash in its

unproblematic property name. (Alternatively, we could have extended the
configuration data used by unit tests with such a problematicaly named
property.)
