Yes, I would expect that the newer version be installed.  I don't know if 
the current libzypp solver handles this case ideally (I mean, it obviously 
doesn't, but I'm not sure if it was supposed to be implemented or not, 
i.e. bug or missing feature), but I believe the new SAT solver will do 
this as expected.

No, I don't think this should be worked around by the packager.  It would 
inevitably lead to problems down the road somewhen.


Ciao,
