I had same problems with my pre-0.5 areas, but I solved them by 
examining 'multipolygon' relations which were created automatically 
during the upgrade. Each such relation holds a list of all "broken" ways 
for an area, so you can select them all and combine into a single way. I 
also then deleted those relations, since they weren't needed anymore.
