createOutline in symbol

Hi All,

I've maked a script to create outline text included in symbol:

Below the script:

#target illustrator
var doc=activeDocument;
VectorizSymbolAll(doc);
//************************* functions for Vectorise Symbol ********************************//
function VectorizSymbolAll(Sfile){
     var SLen=Sfile.symbols.length-1;
     for (si=SLen;si>-1;si--){VectorizSymbol(Sfile.symbols[si]);}
     return true;
     }
function VectorizSymbol(Ssource){
var a=UnlinkSymbol(Ssource); // unlink
gpOutline(a); // create outline for text

var Scopy=Ssource.parent.symbols.add(Ssource.parent.layers.getByName(a.name).groupItems[0]); //make copy of symbol
Scopy.name="Vect of "+Ssource.name; // name it
Ssource.parent.layers.getByName(a.name).remove(); // remove temp layer
replaceSymbol(Ssource,Scopy); // exchange them

Ssource.remove(); //remove original symbol
}
//******************************// 
function UnlinkSymbol(symb){
     var Ltemp=symb.parent.layers.add()
     Ltemp.name="temp"+Math.random(1)*100000; // useless
     var D=symb.duplicate();
     Ltemp.symbolItems.add(D);
     D.remove()
     return Ltemp;
     }
//******************************// 
function gpOutline (groupRef) {
     var textItemsList =  new Array();
     if (groupRef.groupItems.length > 0) {
          for (var i = 0 ; i < groupRef.groupItems.length; i++) {
          var theGroupItems = (gpOutline (groupRef.groupItems));
               for (var j = theGroupItems.length -1; j> -1; j--) {theGroupItems.createOutline();}
          }
     }

     if (groupRef.textFrames.length > 0) {
     for (var i = 0 ; i < groupRef.textFrames.length; i++) {groupRef.textFrames.createOutline();}
     }

     if (groupRef.legacyTextItems.length > 0) {
     for (var i = 0 ; i < groupRef.legacyTextItems.length; i++) {
     var theTextFrame = groupRef.legacyTextItems.convertToNative()
     theTextFrame.createOutline();
          }
     }
return textItemsList
}
//******************************// 
function replaceSymbol(S,C){
for (i=S.parent.symbolItems.length-1;i>-1;i--){if (S.parent.symbolItems.symbol==S){S.parent.symbolItems.symbol=C}}     
     }

//************************* End of function for Vectorise Symbol ********************************//

It seems works perfectly, but once time, it return an error (i don't remember which.. sorry), and now i'm unable to reproduce it

So if anyone can test / martyrize / stress this script and report me any error / mistake / malfunction / a lapse of memory, i will be happy .

Many thanks at all,
