Using the %^C expansion in a capture template brings up a minibuffer prompt to read/select a clipboard value, but there are no values to select from.
The relevant code is in the function org-capture-fill-template. ("C" (cond ((= (length clipboards) 1) (insert (car clipboards))) ((> (length clipboards) 1) (insert (read-string "Clipboard/kill value: " (car clipboards) '(clipboards . 1) (car clipboards)))))) It looks like the intention is to put the list of possible clipboard values into the minibuffer history for read-string, but in practice I get an error saying the history is empty. I suspect that the problem is that clipboard is lexically bound, and since read-string takes a symbol for the history, it cannot get the lexical value for clipboards from the symbol argument.
