OK, tried it on an Ubuntu, and can confirm the segfault:

Writing | ################################################## | 100% 0.04s

avrdude: 336 bytes of flash written

Program received signal SIGSEGV, Segmentation fault.
0x0000000000433f93 in jtagmkII_open (pgm=0x6db9c0, port=0x1 <Address 0x1 out of 
bounds>) at jtagmkII.c:1555
1555      if (strncmp(port, "usb", 3) == 0) {
(gdb) bt
#0  0x0000000000433f93 in jtagmkII_open (pgm=0x6db9c0, port=0x1 <Address 0x1

So "port" is given as 0x01 here.  Stack frame #1 is:

pgm->vfy_led(pgm, ON);

No idea offhand why that triggers a jtagmkII_open() with bogus
arguments.
