[CentOS] Strange ABRT error when I try to switch to su

Hello all

One of my VMs, running RHEL 7, has been giving me the following ABRT error
when I try to login as su     Ive seen this error the past three times that
Ive logged in. I know that the VM is using Red Hat,but seeing that
RHEL/CentOS are pretty much the same thing, I figured I should ask the
CentOS mailing list for help. Here is the error:
