I think that's a bug.

qdisk_spawn_outcome in libxl.c is part of the driver domain backend
service, which is in a special situation.  I still think something
ought to be done with the error, there, but it would have to be
communicated to the toolstack somehow (via xenstore, probably) and I'm
not sure the existing protocol between toolstack and driver domain
permits that.
