Crowbar 0.4.3 not working w/ validated PW

[sidobill]

Hello community.
I'm not being able to reproduce a crowbar test with a actual and functional password.
is there a format list to be using?
here is my command
sudo ./crowbar.py -b rdp -s 192.168.0.xx/32 -u xxxxxx -C /home/ramaz/share/words.txt

and my file contains the following:

duiohdfdf
fds
fsd
fsdf
senha13462
sdf
sdfgjsdigjdfg
dfg
fdss

librdp package needs an active GUI instance to establish and confirm the connection. If you're running head-less or SSH'ing into a VM/Machine - GUI is not active and it fails.
