This is some internal problem in qemu-1.0. You'll need to ask about it
on a qemu mailing list or irc channel - the commandline and error above,
along with telling them your exact version of qemu should be enough to
get them going. (I looked it up in the source and one thing I can tell
you is that the *entire file* containing this assertion ("assert
edp->type == INVALID_EP_TYPE") was removed between qemu-1.0 and
qemu-1.1. It may be that the simplest way to eliminate the problem is to
get a build of qemu-1.1)

Okay, thanks for checking that for me! I will follow up with the qemu project.

Cheers and thanks!
