...given the oldest incarnation of the code still available is

  HACK( "fuer Image, dort gibt es derzeit keine Statics - Bug" )
  if ( ppStaticDefaults )

and

  HACK( "fuer Image, dort gibt es derzeit keine Statics - Bug" )
  if ( ppStaticDefaults )

from cf7e1f9c "INTEGRATION:
CWS visibility03: #i45006# Moved from svtools/source/items/ (for
svl/items1.lib)"...

Impress?) needed a temporary (?) hack there.

Test that assumption by asserting that ppStaticDefaults is non-null.
