after a quick moment of asking google i saw the suggestions that your error
indicates something wrong with the pickled item....which i think in this
case is the font file. is your font file in the right format to be loaded
by fpdf? (i have no familiarity with this error or fpdf so i'm just
throwing out suggestions).
good luck!
