[CentOS] multilib problem during "yum update"

I'm hoping someone can point me to what is wrong here, I can't figure it
out.

running "yum update" on my C7.6 box I get:

--> Finished Dependency Resolution
Error:  Multilib version problems found. This often means that the root
       cause is something else and multilib version checking is just
       pointing out that there is a problem. Eg.:
       
         1. You have an upgrade for libgpg-error which is missing some
            dependency that another package requires. Yum is trying to
            solve this by installing an older version of libgpg-error of the
            different architecture. If you exclude the bad architecture
            yum will tell you what the root cause is (which package
            requires what). You can try redoing the upgrade with
            --exclude libgpg-error.otherarch ... this should give you an error
            message showing the root cause of the problem.
       
         2. You have multiple architectures of libgpg-error installed, but
            yum can only see an upgrade for one of those architectures.
            If you don't want/need both architectures anymore then you
            can remove the one with the missing update and everything
            will work.
       
         3. You have duplicate versions of libgpg-error installed already.
            You can use "yum check" to get yum show these errors.
       
       ...you can also use --setopt=protected_multilib=false to remove
       this checking, however this is almost never the correct thing to
       do as something else is very likely to go wrong (often causing
       much more problems).
       
       Protected multilib versions: libgpg-error-1.13-1.el7.centos.x86_64 != libgpg-error-1.12-3.el7.i686

I don't know what it's complaining about, I have several i686 packages
installed that yum thinks need the libgpg-error package. here's all the
libgpg stuff installed:

libgpg-error.i686                     1.12-3.el7                 @base          
libgpg-error.x86_64                   1.12-3.el7                 @anaconda      
libgpg-error-debuginfo.x86_64         1.12-3.el7                 @base-debuginfo
libgpg-error-devel.x86_64             1.12-3.el7                 @base     

When I encountered this a couple weeks ago I finally excluded libgpg
from the updates, hoping there was some mirror problem that would go
away, but apparently not.

I can't see any reason why having both i686 and x86_64 is a problem,
I'm hoping someone here can enlighten me.

thanks in advance!
