fetch_category_title() accepts anything for $type, even an empty string ( https://code.google.com/p/textpattern/source/browse/releases/4.2.0/source/textpattern/lib/txplib_misc.php#1628 ).

We could have caught [ r3429 ] earlier if fetch_category_title() was less forgiving.

Might use either a constant array of valid types or a set from the txp_category table.
