jasper_reports error ValueError('Invalid literar...')

[filsys]

I can create simple jasper reports and run fine this reports with OpenERP 6 and jasper_reports on my desktop (ubuntu 10.04, oerp 6.0.2, en language). But, when I move all work on server (with same OS, oerp and database), I find this error:

invalid literal for int() with base 10: '17\\\'\\n\'\np6\na. 4701(lp1\ncexceptions\nValueError\np2\n(S"invalid literal for int() with base 10: \'69'

(<type 'exceptions.ValueError'>, ValueError('invalid literal for int() with base 10: \'17\\\\\\\'\\\\n\\\'\\np6\\na. 4701(lp1\\ncexceptions\\nValueError\\np2\\n(S"invalid literal for int() with base 10: \\\'69\'',), <traceback object at 0xc9bf644>)

Does anyone have any ideas?
Thanks
