So, I'm looking at my global todo agenda, and I'd like to change the state
of the task under the cursor.
According to the doc, 't' should let me do that, but when I hit 't', I get

> wrong type argument: stringp, nil

which isn't really doing it for me as an explanation of what I'm doing
wrong.

Thoughts anyone?
Cheers.
