Description Adam Cox 2011-09-24 05:45:36 UTC 
Warning: preg_match() [function.preg-match]: Empty regular expression in /home/zeldaw/public_html/includes/Linker.php on line 1466

After upgrading to MediaWiki 1.17.0 and PHP 5.3.2, I found that this extension generated the above error on our wiki. Since I couldn't find anywhere in CharInsert.php which was obviously making a call to this (or any) function in Linker.php, I instead went to includes/Linker.php to analyse the indicated line. 

I found that I could work around this by modifying Linker.php to comment out line 1459 (if ( $regex === false ) {) and the closing brace on line 1462, such that the error is no longer generated.

code is different in 1.18.  Probably will be solved by an upgrade to that version (tarball to be released shortly, but you can use the 1.18 branch since that is live on WMF wikis).
