OSMI should pick up multipolygon relations whose outer rings double back 
onto themselves. However, depending on the exact situation it is 
possible that things are a little counter-intuitive because:

* if a way doubles back onto intself (e.g. nodes A-B-C-D-C) then it will 
show up on the general "geometry" layer;

* if all ways are ok but only when combined into a multipolygon you have 
it doubling back (e.g. way 1 = A-B-C-D, way 2 = C-D), then it will show 
on the "multipolygon" layer.

If you encounter a bug that is not shown on any of these I would be 
interested to hear details.

Bye
Frederik
