Looks OK, so if you're confident that the data is the same then I'm not 
sure where the problem would be. I would double check everything because 
  I'm confident this is not a bug in libfprint. Double check the buffer 
you are passing in, perhaps print the first 3 characters to the console 
before you do (it should be FP1 ascii).

It really does not make sense -- you are telling me that if you pass in 
a buffer in 1 environment (fresh from the scanner) then it works, but if 
you let it chill in the database a while and then pass in an identical 
buffer it fails.

You could enable debug messages in libfprint. There will be a debug 
message printed for every rejection condition in 
fp_print_data_from_data(). Please show full output from a failed run if 
you do this.
