Reading the comments at it seems a workaround has been found.

I reassigned this bug to quemu maintainers. They should consider to temporary disable smartcard support, because any VMs fail to run if a virtual smartcard device requested.

Debian report:

It's already fixed by upstream:;a=commit;h=e58d64a

Please apply this patch for qemu.

The upstream patch has been cherry-picked into qemu 2.12.0-2 (currently in [testing]). Please try it and let us know the result.

Installed qemu 2.12.0-2 from testing. It works for me! Both for Fedora 28 and Windows 10.
