1.6.5. Child theme no longer working

/*
Theme Name: My JobRoller Child Theme
Version: 1.6.x
Description: A child theme for JobRoller, the premium job listing theme for WordPress.
Author: John Doe
Author URL: http://www.itstoolong.com
Template: jobroller
*/
@import url("../jobroller/style.css");

Activating the 1.6.5 theme seems fine, but when I activate the child theme (even without any .css in it - see above) it just breaks the whole layout (i.e. content + sidebar layout changes to full-width layout).

What am I doing wrong?
