I encountered the following error on opening the update window (there are 14 available updates).
Traceback (most recent call last):

"later." % (srcpkg, srcver),
NameError: global name 'srcpkg' is not defined
I'm using PackageKit 0.3.1 installed from the PPA https://launchpad.net/~packagekit/+archive on Ubuntu Intrepid 32 bit.
I've just fixed this in f057bf5875b42f990afdd140a0377ed8c070c609 -- many thanks for reporting it.
