NS_ERROR_FAILURE is returned with nsISyncLoadDOMService::LoadDocument

[Hing-Wah Wan]

Hi,
	I'm using the attached code trying to construct a DOMDocument from a 
url,however, I get NS_ERROR_FALURE  return code from 
nsISyncLoadDOMService::LoadDocument. I don't have a debug build but the 
problem look like in nsSyncLoadService.cpp:403 ( 
http://lxr.mozilla.org/mozilla1.7/source/content/base/src/nsSyncLoadService.cpp#403) 
while tracing the assembly code . mLoadSuccess seem to be false. What's 
wrong with it? I'm using mozilla 1.7.5 on debian sid.

Thanks
