One thing to try is to do polygonize and then issue a buffer(0) on the  
results of the polygonize.  buffer(0) is (one of) GEOS' way of  
tripping the segmentation routines, and it might produce a multi* that  
contains your cleaned polygon (plus everything else).

I don't know if this will work, but it's something to try if you  
haven't already.
