Indeed it should, though like you, I am not sure why. with the date
change, the release is higher and should be a clear update. When I
tried to submit the update to bodhi, I got the same thing. Though I am
doing another update today.
RPM version comparison is not hexadecimal. You need to split the value
into numerical and non-numerical parts:
// full value
# rpmdev-vercmp 20110718525e3df 2011072859fadcc
20110718525e3df > 2011072859fadcc
that's the one you wondered about
// just the numerical/decimal prefix, longer one wins
# rpmdev-vercmp 2011072859 20110718525
2011072859 < 20110718525
// just the decimal prefix, longer one truncated, hence it loses already
# rpmdev-vercmp 2011072859 2011071852
