Arrgh! I've worked out what's happening here: basically  
pglwgeom_serialize() alters
its input geometry which should be a total no-no. The fix should be to  
remove this
horrible piece of code from pglwgeom_serialize:

#if POSTGIS_AUTOCACHE_BBOX
         if ( ! in->bbox && is_worth_caching_lwgeom_bbox(in) )
         {
                 lwgeom_addBBOX(in);
         }
#endif

and then go around the rest of the codebase fixing up any callers that  
require it.


ATB,

Mark.
