It would be better to just explain what is actually happening.  The 
libxklavier package provides three things:

[5610] gholms@lux ~ % rpm -q --provides libxklavier.x86_64
libxklavier.so.15()(64bit)
libxklavier = 4.0-7.el6
libxklavier(x86-64) = 4.0-7.el6

The first of these is the library itself, namely 
/usr/lib64/libxklavier.so.15.  rpmbuild automatically adds dependencies 
of this type to packages that link against shared libraries.

The rest are used for things that depend on the package by name.  For 
instance, this includes gnome-applets-2.28.0-7.el6.x86_64's dependency 
on "libxklavier >= 4.0".

By having yum remove the libxklavier package you remove all three of 
these, but your rpm query only searched for things that depend on the 
second.  To get an accurate list of what directly depends on a package 
you must check *everything* that the package provides.

[5616] gholms@lux ~ % rpm -q --provides libxklavier.x86_64 | sed 
's/=.*//' | xargs rpm -q --whatrequires | sort | uniq
control-center-2.28.1-25.el6.x86_64
gdm-2.30.4-21.el6_0.1.x86_64
gnome-applets-2.28.0-7.el6.x86_64
gnome-screensaver-2.28.3-8.el6.x86_64
gnome-settings-daemon-2.28.2-11.el6.x86_64
kdebase-workspace-4.3.4-19.el6.x86_64
libgnomekbd-2.28.2-2.el6.x86_64
libxklavier-4.0-7.el6.x86_64
no package requires libxklavier(x86-64)
