My testcase did freak out the split code. I print the ofs and it values used in deletesectionrange and end up with an invalid ofs (it is negative) possibly because one of the original start values was 0xffffffff ? I am not sure.

I will try to track this down.

in split 9444436 418
in split 4220892 194
in split 976 196
in split -9443580 198

Traceback (most recent call last):

dataout = dataout[:first_pdb_record+i*8] + struct.pack('>L',ofs) + struct.pack('L',it) + dataout[first_pdb_record+i*8+8:]
struct.error: integer out of range for 'L' format code

Kevin - if you pm me the file I'll debug the mobi_split code
