Comment (by strk):

 Ok I can reproduce with:

 > NOTICE:  Corrupted topology: face 1098 could not be constructed only
 from edges knowing about it (like edge 2978).
 > ERROR:  Programmatic error ? Geometry of face 1098 is empty!

 A NOTICE message indeed reports an invalid topology:

 > NOTICE:  Corrupted topology: face 1098 could not be constructed only
 from edges knowing about it (like edge 2978).
 > ERROR:  Programmatic error ? Geometry of face 1098 is empty!

 So we probably have a bug in ValidateTopology which indeed does not report
 any error about having an empty face.
