it crash inside teh closedsource divx4linux lib.
i cannot do much with it :(

0x4016f110 <signgam+19120>:     cld
0x4016f111 <signgam+19121>:     mov    bashxa,%ecx
0x4016f116 <signgam+19126>:     repz movsl %ds:(%esi),%es:(%edi)
                                ^^^^^^^^^^ crash here

anyway teh asm dump is interesting, but unfortunately incompleter (register
values missing). it is required to know at least esi, edi and ecx here.
mayeb one of them is zero.
