help tracking down bad setting?

[Matt Price <moptop99@gmail.com>]

Hi everyone,

When I load org-mode I get the following error:

local-set-key: Key sequence C-c SPC C-r starts with non-prefix key C-c SPC

I am pretty sure I set something to this value somewhere at some time,
but I have no idea what, where, or when.  I have grepped through

.emacs
.emacs.d/*

for local-set-key, "C-c SPC C-r" and "SPC" and I haven't found anything.

org still seems to run, but some process is interrupted, I think ,as
any function which calls (org-mode) will not run any code after that
call.

What do you think -- where should I look, and what should I search for?

Thanks a lot,

Matt
