Given the limitation of having to have a single line output in the
error message, this seems like it's doing the right thing to me.

You can (painfully) rewrite the error message to make it look like the
original:

Traceback (most recent call last):
  File "/home/nsoffer/src/libguestfs/tmp/v2v.ayEM8r/rhv-upload-plugin.py", line 373, in pwrite    (offset, count))
  File "/home/nsoffer/src/libguestfs/tmp/v2v.ayEM8r/rhv-upload-plugin.py", line 321, in request_failed    raise RuntimeError("%s: %d %s: %r" % (msg, status, reason, body[:200]))
RuntimeError: could not write sector offset 1897857024 size 65536: 403 Forbidden: b{"explanation": "Access was denied to this resource.", "code": 403, "detail": "Ticket u'acdad591-f29e-4d85-bf41-046e250aa015' expired", "title": "Forbidden"}

So it looks like all the information is still there, particularly
about the expired ticket.

Thanks for testing this,

Rich.
