NS_InitEmbedding Crash

[Abhilash Maniam]

Hi,

I have the following lines in my code:

 nsCOMPtr<nsILocalFile> greDirectory;
 nsresult rv = 
greDirectory->InitWithNativePath(NS_LITERAL_CSTRING("c:\\mydir\\gre\\1.4f_2003062480"));

 if(NS_FAILED(rv)) {
    return rv;
  }
 rv = NS_InitEmbedding(greDirectory,nsnull);
My program crashes. I am working on Windows xp professional, with 
mozilla 1.4b build. What could be the possible reasons.

Thank you.
