Virtuoso odd DBUUU scale problem

I have a GDSII layout of a test mask with 1nm database units and 1.0 DBUUU
(1nm user units). When streaming into Virtuoso 5.0.33, I get a warning:

WARNING (164): Bad unit information found in the Stream file. `U-UNIT/DBU':
`1.000000e+00','METRIC/DBU' : `1.000000e-09'.1. scanning cellview (fang_test
layout)

And a lot of:
*WARNING* Rectangle being created has no area

When I try to open the created cell in Virtuoso, it runs the machine out of
memory (> 1GB), even though the cell is very small, and I have to kill the
process. What is going on? Is there a way to stream this into Virtuoso and
display/edit it without problems?

Thanks.
