Which version of libfprint are you using? apt-get version or did you
compile it yourself? I remember a thread some months back about the
Debian default libfprint was rather old, so this might be your issue.

If you compiled by yourself, you can recompile with a debug switch when
configuring (--enable-debug-log), which will make the library spit a lot
of information out...
