I've already reported this to the Ubuntu folks (CC'ed), and they have
assured me that this will be addressed before the final release.

Logging a bug here would probably still be a good idea as a reference as
other Ubuntu users run into this issue.

So the problem is the mixing of the Fedora forked version of rtslib-fb,
and upstream targetcli codebase. rtslib-fb is *not* object library
compatible with upstream rtslib, which is what is causing the breakage
here.

Note this issue is specific to the rtslib_2.1.fb27 package in Raring,
and using the Quantal package below with the upstream rtslib version
should get you up and running again:

http://packages.ubuntu.com/source/quantal/rtslib

Thanks for reporting!
