hm, ok, the caller of this function does not check that the Geometry
actually does have types (in other words it assumes the Geometry is
valid without checking).

It's a mixture of your model containing Geometry without types (which is
normally considered invalid - you should see a warning like:
"WARNING: masterPump: Geometry 0x1d44df0 has no Types!" in the log when
the display list is compiled). The other problem is that the geometry
merging code is perhaps a bit too optimistic and should check for
invalid geometry instead of crashing. I'll add some checks.
Cheers,
Carsten
