transaction checks error on updates fc7

["Gianluca Cecchi" <gianluca cecchi gmail com>]

It seems that updates yum tries to apply generate inconsistencies.
my system is x86_64 and I noticed that for several packages I have
different versions installed for x86 and x86_64.

One example is esound for which the x86 rpm currently installed is
something like 2.0.36, while the x86_64 one installed is 2.0.37.
And yum tries to update to 2.0.38 but then it fails due to conflicts
with 2.0.36...
Similar things for esound.

Any hints?
