F14 - PackageKit vice yum update discrepancy

[JB]

Hi,

This is F14.

I tried an update:
menu: System-Administration-Software Update (which is PackageKit)
...
Transaction error:
could not add package update for
sane-backends-libs-1.0.22-5.fc14(i686)updates:
sane-backends-libs-1.0.22-5.fc14.i686

which means the update process was interrupted and canceled.

# yum list sane-backends-libs
...
Installed Packages
sane-backends-libs.i686                  1.0.22-3.fc14                  @updates

sane-backends-libs.i686                  1.0.22-5.fc14                  updates
#

Next I tried update with yum:
# yum update

Why the difference ? Perhaps there is an error in one of the update packages ?
