I haven't made a detailed analysis, but it seems that one of the tracks in that MIDI file you provided specifies an incorrect byte length. Fluidsynth recognizes this "buffer overflow" and cancels parsing the file. Here's a more verbose console output, which is currently only visible in debug builds, unfortunately:
