Automattic Stats, or PHP 5.2.2 vs. WordPress XMLRPC

Experimenting with the new Automattic Stats Plugin that uses the WordPress.com statistics infrastructure to track traffic. So far, so good… except for one problem. Titles and links are missing from all the “most visited” posts. They’re just listed as numeric IDs.

Update: Actually, today’s posts seem OK. The plugin seems to just send the blog ID and post ID. I’ve been trying to figure out how the central server is retrieving the permalink and title. It doesn’t look like Bad Behavior is blocking it. And it doesn’t seem to be using the RSS feed, since posts that are still on the front page (and presumably still in the feed) are also showing up as numbers. *grumble*

Update 2: I just noticed that all of the number-only posts show the same placeholder graph showing “Region A” vs. “Region B” for 2003-2005.

Update 3: It’s a problem with WordPress’ XMLRPC interface, and affects other uses (like connecting with Flock). I’ve got a workaround, though (see comments).

Update 4 (May 10): Thanks to the pingback below from dot unplanned, it’s confirmed to be a bug in PHP 5.2.2. With any luck, the workaround will cease to be necessary when the next PHP bugfix is released.
