I am not sure if this is a new bug or what...

Am using the module (ie_css_optimizer 6.x-1.1) for development site.

The bug happens when the option for "Bandwidth optimizations" is set to "Partial optimization for theme CSS development" (admin/settings/performance) and there seems to be some inline CSS is missing.

Could this be related to Incompatibility with ctools (http://drupal.org/node/956416)?
