Yes, please open bugreports for both problems and provide small
standalone examples and explain expected behaviour in each case.

As the dependecy resolution is now hapenning also during the build, I see that the ".qualifier" dependency for the product is correctly resolved against local repo. However the product publisher seems to ignore this and expands the qualifier with the build timestamp. So in (3), it is apparently a problem with the publisher. Should I open a bugzilla for this?
