I have the same issue… And no idea so far what to try next 
tried diffrent full planet osm… so I think database should be ok… although i get the follinwing exception during import…
Standard exception processing way_id 1683435: TopologyException: side location conflict at -8.01753e+06 -4.82195e+06
everything continues normally…
I think it has something to do with this Kay Krueger package… But I got no idea how to get rid of it completly to try a fully manual install…
best regards,
Stefan
