Todo mode crashes when activated in an empty, file-less buffer.
Reproduced by the following recipe from Emacs -Q:
1. Switch to a new buffer, so that it's empty, and not connected to
a file.
2. Run `M-x todo-mode'.
This should produce the following error message:
todo-mode: Wrong type argument: arrayp, nil

Thanks for the report. Before I try to fix this, I'd like to know why
you carried out the above recipe: did you just happen to discover that
Emacs has this package and wonder what it is and so just decided to
invoke todo-mode in an empty buffer and see what happens? The reason
I'm asking is that `M-x todo-mode' is not one of the documented entry
points, and in normal operation of Todo mode it should never be
necessary to call todo-mode. Moreover, most of Todo mode is not
designed to work with non-file buffers; there are exceptions, but they
are (intended to be) available only after you've added at least one todo
file, by typing `M-x todo-show', as documented (both in the Commentary
of the source code and in the Todo Mode Info manual). So knowing why
you typed `M-x todo-mode' on an empty buffer will help me to decide how
to avoid the error. Thanks.

Yes, that's it. I noticed it in the 24.4 release notes, and wanted to
check it out, so I typed `M-x todo-mode' to see what happens.

Ok. This is a reaction I admit I (probably foolishly) didn't
anticipate. If you are still interested in trying out Todo mode, please
type `M-x todo-show'. In future, and for others to avoid the problem
you encountered, it may be best to just make interactively invoking
`todo-mode' call `todo-show', but I have to think about it a little
more.

I committed a fix to the emacs-24 branch: now if todo-mode is called
interactively, there's no error and a message is displayed saying to
call todo-show to enter Todo mode.
