I will send a patch as soon as I can, but these lines in WMFRecordStore:

if (_bext && functionId == WMFConstants.META_SETWINDOWEXT) {
   vpW = width;
   vpH = height;
   if (! isotropic) scaleXY = (float)vpW / (float)vpH;
   vpW = (int)(vpW * scaleXY);                      
   _bext = false;
}

should be changed to:

if (functionId == WMFConstants.META_SETWINDOWEXT) {
   if ((width > 0) && (height > 0)) {
       vpW = width;
       vpH = height;
       if (! isotropic) scaleXY = (float)vpW / (float)vpH;
       vpW = (int)(vpW * scaleXY);  
   }                    
}

Of course, _bext is not useful anymore. The check for width and height being
greater than 0 is "just in case". There are so many faulty WMF files in the
wild ;)
