If you frequently switch between Lisp and other languages, you probably
have to strain to get out of the mode of seeing single quotes as
surrounding delimiters rather than just a prefix.
The Lisp parser sees that as
(put-text-property (point-at-bol)
(point-at-eol) 'face ''default)
which explains the original error. ''default is short for '(quote
default).
