I'm using K2 svn with Joomla 1.7.1

When wanting to make a new account on the frontend wiyh the K2 Login module , the following error appears: Fatal error: Call to protected method JView::_addPath() from context 'plgSystemK2' in /home/..../templatename/plugins/system/k2/k2.php on line 193.

The same error appears when logged in (with an account made in the back-end) and trying to open the link My Account.

 

I've tried the K2 Login Module on several other websites with K2 SVN and Joomla 1.7 and the same error keeps appearing.

Anybody an idea what's going on and how to fix this?
