I faced this bug as well, though in a slightly different fashion:
I was using extlinux directly to install syslinux a USB pendrive and boot a custom Linux distro off it. All well until this bug hit, i,e, Wily's version of syslinux!
Thanks to Praveen B - your comment workaround helped me install the working package from Vivid Vervet, and all worked again.
