Can't print any Jasper report with OpenERP multiprocessing (workers)

Hello,

When OpenERP is NOT working in Multiprocessing Mode, then everything works fine, but if OpenERP is working with Multiprocessing Mode (using --workers parameter), then no Jasper report works.

When I try to print any report I get this:

2014-03-01 20:29:12,817 5764 INFO TM_DATOS_REALES openerp.addons.jasper_reports.jasper_report: Requested report: '/mnt/hgfs/IsraelCA/opt/openerp/70openerp/jasper-reports/jasper_reports/custom_reports/poliz.jrxml'
