domain mapping update breaks site

Hi

Updating the Domain Mapping plugin from 4.4.0.9 to 4.4.1 resulted in the following error message:

Fatal error: Call to a member function getRequestUri() on a non-object in /srv/www/vhosts/21-experts.com/httpdocs/wp-content/plugins/domain-mapping/classes/class.domainmap.php on line 476

Copying the old 4.4.0.9 version of the plugin from another installation brought back my site.

Was this me, or is there a bug in the new version?

Best
Wolfgang
