Patch to fix null object bug (355 bytes, patch)
2006-09-08 20:32 UTC, wclark

Description Nick Jenkins 2006-08-01 07:43:51 UTC
CURL command:
curl --silent --include \
 -F 'url'='x' \
 -F 'blog_name'=\
 -F 'article'='\</H2>'\
 -F 'title'='Main Page'\
 -F 'excerpt'='BLAH'\

LocalSettings.php includes this: 
$wgUseTrackbacks = true;
error_reporting (E_ALL);
(i.e. stricter error reporting, and trackbacks usage enabled).

Resulting HTML output is:
<br />
<b>Fatal error</b>:  Call to a member function exists() on a non-object in
<b>/var/www/hosts/mediawiki/phase3/trackback.php</b> on line <b>53</b><br />
