Yeah, Skype requires a bunch of 32-bit libraries.  It's usually
harmless, although you seem to have run into a glitch.

YUM ensures that when you have x86_64 and i686 libraries installed,
they both stay at the same version.  (Things can get screwed up pretty
badly if their versions differ.)  For some reason, YUM found an update
for the i686 version, but not the x86_64 version, so it failed out
rather than install it and potentially screw up your system.

>From here I can see that the new gtk2 is present for both x86_64 and
i686, so likely your YUM metadata is outdated/incorrect.  "yum clean
all" will erase it and force it to redownload on the next update.
