   //getElementsByTagNameNS is defined but still throws error in IE7

We incorrectly specified a data-path and data-htc-filename which also included 
the path. Any improper definition causes 
FlashHandler._prepareBehavior
// attach SVG behavior to the page
ns.doImport(libraryPath+htcFilename);
to concat an invalid filePathName resulting in .htc not to load. No errors are 
thrown.
We have added a check in our startup for our stupid mistakes:
if(!gSVGDOMDoc.getElementsByTagNameNS) {
   console.error("_SVG:onLoad: .htc not loaded/initialized");
   return;
}
