I tried the same with cache=directsync on the guest.
I get almost the same result:

Aug 19 16:57:50  ERROR [gway 31433] wait_forward_request(212) fail
4fd26d00000003, No object found
Aug 19 16:57:54  EMERG [main] crash_handler(250) sheep exits
unexpectedly (Segmentation fault).

But sheep daemon is still running!

dog node list hangs up.
qemu is still running (guest shows I/O error) and I have to use kill
-9 to stop it.

More messages in sheep.log
