[pstricks] Strange compilation problem

[Łukasz Wieczorek]

Hello,
I would ask for help in sloving a problem with my presentation. It 
stoped to compile when I added the pspicture environment.
The error is
"! Argument of \language at active@arg" has an extra }.
<inserted text>
                 \par "
Tex file attached.
Thank you for your time.
Lukas
