I think this is either a bug in the firmware or the model of kindle reader.
I have a PW2 with 5.9.7 firmware. I'm using custom fonts very happily and (touch wood) have had no problems. I was told to put all versions of the font (regular, bold, italic, italic bold) as not doing this can cause crashes - the only issue I found was that it didn't render the missing font type, italic for example.
The OP's issue seems to be a bug in the notorious 5.10.2 firmware, maybe.
