Detected bug in an extension![edit]

I get the following output by Mediawiki 1.12.0 on Debian and Axion Version 20050901-9:

Detected bug in an extension! Hook wfAxiomInitPerPage failed to return a value; should return true to continue hook processing or false to abort.

Backtrace:

#5 /var/www/mediawiki-1.12.0/index.php(90): MediaWiki->initialize(Object(Title), Object(OutputPage), Object(User), Object(WebRequest))

Why? How can I solve this problem?
