I'll answer my own post. My problem was in ParserFunctions. For some reason the SVN was pointing to a branch of extensions below the 1_13 release instead of:
http://svn.wikimedia.org/svnroot/mediawiki/trunk/extensions/ParserFunctions
Switching SVN to that version of ParserFunctions seems to have removed the error.
Hope that helps someone else.

I'm wondering if anyone else has this. It took me a few days to spot this as I forgot to check my error logs but now I see I've had 16meg of errors over a weekend on a development site that gets very little traffic. Since upgrading (with svn) my logs are full of:
[Fri Aug 01 12:38:01 2008] [error] [client 67.90.55.2] PHP Warning: preg_match() [<a href='function.preg-match'>function.preg-match</a>]: Compilation failed: PCRE does not support \L, \l, \N, \P, \p, \U, \u, or \X at offset 3 in /var/www/vhosts/ adv01.mysite.com/httpdocs/w/includes/Linker.php on line 1364, referer: http://adv01.mysite.com/w/index.php?title=Fitzgerald:_Second-class_citizens%...
Problem?
