DNF Crash Installing Package and Resolving Keys

[Stephen Morris]

Hi,
     I was trying to install mysql packages from the yum repository for 
Fedora 20 provided by Oracle and the fist package dnf tried to install 
needed to have a key loaded from the key file specified in the 
repository definition but crashed with the following stack trace. Has 
anybody else seen this?
     As a side issue to this, after getting the failure I tried sudo yum 
upgrade and that just kept looping complaining that yum-cron was holding 
the yum lock, is this normal?
