It seems these CSS files are included from several controllers. I'm not that familiar with Yii, however since its mvc shouldn't css includes be defined in a view / layout?

-- The easy fix is obviously just to fix the paths; if you want me to do this assign the bug to me. A better / nicer fix would be to remove this code from the controller and move it to the view / layout instead...

application/controllers/admin/participantsaction.php:
$this->getController()->_css_admin_includes(Yii::app()->getConfig('generalscripts') . 'jquery/css/jquery.multiselect.css');

application/controllers/admin/surveyadmin.php:
$css_admin_includes[] = Yii::app()->getConfig('generalscripts') . "jquery/css/jquery.multiselect.css";

application/controllers/admin/conditionsaction.php:
$this->getController()->_css_admin_includes(Yii::app()->getConfig("generalscripts").'jquery/css/jquery.multiselect.css');

application/controllers/admin/tokens.php:
//$this->getController()->_css_admin_includes(Yii::app()->getConfig('generalscripts') . "jquery/css/jquery.multiselect.css");

Aaron, what do you think would be the best approach?

Sorry - I got lost in my project and forgot about the tracker. I don't know the "rules" of mvc too well, but I know that there are literally hundreds of js and css includes that would need to be altered, and it seems that we're not at a good point in the release cycle to do that so I propose we just fix the paths for now.

https://github.com/LimeSurvey/LimeSurvey/pull/19 seems to work for me. Merge it if you can confirm.
