If the enumerator returns several times the same path the problem could not be 
a mdextractor bug.
Can you, please, compile and run this:

int main(int argc, char** argv)
{
  CREATE_AUTORELEASE_POOL(pool);
  NSDirectoryEnumerator *enumerator = [[NSFileManager defaultManager] enumeratorAtPath: 
@"/home/philou/stuff/winedata"];
  NSString *fname;

  while ((fname = [enumerator nextObject]) != nil) {
    NSLog([path stringByAppendingPathComponent: fname]);
  }

  RELEASE (pool);
  exit(EXIT_SUCCESS);
}

If the behaviour is the same, that is, 
"/home/philou/stuff/winedata/drive_c/windows/temp/vs60wiz.exe" is returned many 
times, or there is a bug somewhere in -base or you have a problem with your disk...
