Crystal report 13.0.2 document.ExportToStream html40 file not found issue

Question

when export to html, it seems like the html file is exported suessfully but when it is reading the file back, it said the file is not found. but by opening up the temp folder, the file is there but with the .html extension instead of the reported missing file with the .htm extension. bug?

hi Don,
here's the code used:
var stream = document.ExportToStream(ExportFormatType.HTML40);                           
that's where the exception is thrown. with reflector, the code boil down to this:
HTMLFormatOptions htmlFormatOptions = new HTMLFormatOptions();
      htmlFormatOptions.HTMLBaseFolderName = (string) null;
      StringBuilder stringBuilder = new StringBuilder();
      stringBuilder.Append("cr_export_");
      stringBuilder.Append(Guid.NewGuid().ToString());
      stringBuilder.Append(".htm");
      string path = Path.Combine(Path.GetTempPath(), ((object) stringBuilder).ToString());
      htmlFormatOptions.HTMLFileName = path;
      htmlFormatOptions.HTMLEnableSeparatedPages = false;
      reqContext.ExportInfo.ExportFormatOptions = (ExportFormatOptions) htmlFormatOptions;
      HTMLExporter htmlExporter = new HTMLExporter(this, reqContext);
      htmlExporter.Export();
      FileStream fileStream = new FileStream(path, FileMode.Open, FileAccess.Read, FileShare.None);
      try
        MemoryStream memoryStream = new MemoryStream();
        try
          byte[] buffer = new byte[4096];
          int count;
          while ((count = fileStream.Read(buffer, 0, 4096)) > 0)
            memoryStream.Write(buffer, 0, count);
          if (memoryStream != null && memoryStream.Length > 0L)
            return (Stream) memoryStream;
        catch
          memoryStream.Close();
      finally
        if (fileStream != null)
          fileStream.Close();
        htmlExporter.RemoveTempFiles();
notice the line
htmlExporter.Export(), think that's where it generate the whatever.html page, but notice the path building logic, it use .htm but not .html.
is it not a bug? I open up the temp folder and see the .html file but not the .htm file.
