we've update vdsm package within oVirt 4.1.0 Second Release Candidate fixing:
Bug 1416112 - virt-v2v: Import from VMware, Xen and KVM failed with "OSError: [Errno 9] Bad file descriptor" (workaround: upgrade python-cpopen) 
Being the fix just forcing Requires: python-cpopen >= 1.5 instead of Requires: python-cpopen >= 1.4
and being python-cpopen >= 1.5 already availablein RC2, GA shouldn't have any delay.
