rowcount() outputs number of rows 0

[GoogleCodeExporter]

What steps will reproduce the problem?
1. try to read large excel sheet that has 65536 rows.
   $xls = new Spreadsheet_Excel_Reader("filename.xls");
   echo $xls->rowcount();

What is the expected output? What do you see instead?

Expected : It should output the number of rows int the sheet.

Current : Output is 0.

Please provide any additional information below.

Note : It gives correct number of rows for a file with less number of rows. 
(e.g: i tried with a sheet that had 500 rows)
output : 500
