Gothic 1 blocking does not work

[rokuroo32]

Hello,

I'm currently playing Gothic1 with "./Gothic2Notr.sh -g1 -rt 1 -g ~/Documents//Gothic". There is one bug in the fighting system: I can't block. When I played the steam version blocking worked. There is no blocking animation when Im in fight mode and press the back key and action key which works fine in normal Gothic.
