I'm not familar with NTLM protocol, but in my case NT password seems to
be empty (length 0). In this case, older version of helper accept it.
The new one exit with error "insane data". That why I propose to test if
len is not null.
NT password is empty with cNTLM but also with firefox on a GNU/Linux
workstation.
