Modal window style gone after upgrading jQuery UI module

It looks like the latest version of the jQuery UI module (v6.x-1.5) changed the location of the ui themes directory, so the ui.all.css file is not being added properly by this module. The jQuery UI themes directory is now located in the jQuery UI library folder at /sites/all/libraries/jquery.ui/themes/default.

I fixed the issue by changing line #58 in epsacrop.module from:

drupal_add_css(drupal_get_path('module', 'jquery_ui') .'/jquery.ui/themes/default/ui.all.css');

to:
drupal_add_css('sites/all/libraries/jquery.ui/themes/default/ui.all.css');

Hope that helps anyone who experiences the same problem.
