[fprint] etes603 error

[Patrick Marlier]

Hi Paolo,

Just to tell you that I can reproduce the problem on my machine. However 
I have no clue yet on why it happens with the enroll example. I am not 
sure when I will have time to dig more so you can try to use 
fprintd-enroll (it was working months, or years ago).

Regards,
