Cannot modify templates (partitioning and otherwise) after v1.10 to v1.11.1 upgrade via yum

I just did my normal 'security updates' and encounter internal server
error. I can't modify users, templates, etc. I just get horrid errors in
the apache logs: I did submit a bug log:

14918 in the tracker just to be a good citizen.
