I already know about that fix but the problem is that the .gcf only contains .dll files and no linux .so files 
Thanks anyway
EDIT:
Here it is
Stop your server
Backup your orangebox/bin/engine_i486.so
Upload the downloaded engine_i486.so to your orangebox/bin folder
Restart your Server
Thanks to Violentcrimes for sharing the "old" engine_i486
