Empty challenge text during interactive login under wxGTK

Description
Problem: I'm using GRC's PPP for passwords. The idea is that you have a paper card with you with lists of passcodes. When you log in, the server asks you for your password and then asks you for a passcode on the card. This is accomplished through challenge-response (interactive keyboard-based) SSH authentication. Filezilla does not ask the challenge that the server asks.
How to reproduce: Install Filezilla 3.03 on Ubuntu Gutsy. Install ppp-pam and configure it for SSH (located at http://code.google.com/p/ppp-pam/) Open Filezilla, configure it to log in using SFTP, then choose the interactive login method. Connect to the server.
What happens: The interactive dialog pops up, but it is blank and it doesn't ask which passcode to enter. See this screenshot: http://i12.tinypic.com/7wffgqq.png FileZilla should be asking for "Passcode 3A [1]", but the challenge box is blank. However, if the correct passcode is entered, the server authenticates me.
Again, I'm using FileZilla 3.0.3 with Ubuntu Gutsy.

ppp-pam doesn't compile on my systems (badly written code it appears), would it be possible to get a temporary guest account on your server to analyze this further?

Beautiful! Gee, thanks a ton. This helps me a *lot*. Back to FileZilla from WinSCP it is!
In the interest of security, i've removed that guest account. Go ahead and email me if you need it back. hotdog003@…
