Hi List!
I upgraded Ceph to the latest development version
Commit: 0edbc75a5fe8c3028faf85546f3264d28653ea3f
Pulled from: git://ceph.newdream.net/ceph.git
I recompiled the latest GIT version of QEMU-KVM (with Josh Durgin's
patches) against the latest git version of Ceph.
However, this error is still occurring:
terminate called after throwing an instance of 'ceph::buffer::end_of_buffer'
what(): buffer::end_of_buffer
Aborted (core dumped)
Here's another backtrace from GDB:

I haven't seen that error before, but it's probably a bug in the OSD
where it doesn't set an error code. If you've still got the core file,
could you go to frame 10 and send us the values of r, bl._len, and iter.off?
Thanks,
Josh
