Cache must be active error

[Colin Baxter]

I now find that when I enter `m' to match an agenda TAG/PROP/TODO, I get
an error telling me that the "cache must be active". This error is new
today and I assume the result of commit 948c89644.

I have

(setq org-element-use-cache nil)
(setq org-element-cache-persistent nil)

Is there a solution for those of us who do not wish to use org cache
(and org-persist)?
