Problem to read a xlsx file saved with libreoffice

[GoogleCodeExporter]

I have a xlsx file, generate with Excel program, and I open it with libreoffice 
(under Ubuntu). After I saved it in xlsx format, php-excel-reader make an error 
like :
Fatal error: Uncaught exception 'PHPExcel_Calculation_Exception' with message 
'Maubert!B2 -> Formula Error: An unexpected error occured' in 
/var/www/transect/plugins/phpExcel-1.8.0/Classes/PHPExcel/Cell.php on line 300

If the file is saved as ods file, it can be loaded (but others errors occur).

Tanks,

Eric.
