There is a sample link, /api.php?action=feedwatchlist, that when clicked shows: Catchable fatal error: Object of class RSSFeed could not be converted to string in /var/lib/mediawiki/includes/normal/UtfNormal.php on line 221
Unable to reproduce on http://en.wikipedia.org/w/api.php?action=feedwatchlist
OK, added the URL I should have previously. Maybe you can probe it with different queries. Or I can send you the SQL of whatever table you need.
This sounds like a bug in the UTF-8 normalization code that was fixed a while ago. Works for me on SVN HEAD, which you also seem to be running.
OK, now it says Error (wlnotloggedin) You must be logged-in to have a watchlist so it is probably fixed.
