It's actually a problem with Google minify, the JS/CSS compressor used in the manager, and something we're working on for 2.2-pl. For now, you can just turn off CSS/JS compression and that will fix the issue (turn off compress_css and compress_js system settings).
Does anyone know if this was fixed in 2.2-pl? I've had issues in with 2.2 in Chrome where minify causes errors on some manager pages, specifically the System Settings and Actions pages:
Uncaught SyntaxError: Unexpected token < index.php:12
Works ok in Firefox but these pages end up blank in webkit browsers. I've disabled compression in all 2.2 installs but would prefer to have that performance boost if possible
