After updating Drupal core to 7.24 a few days ago,
we witnessed multiple 404 errors (for css and js aggregate files) for anonymous users
in the console (see attached image) causing the theme to break.

This was witnessed on Omega 4 - 7.x-4.0, but also happened after updating to 7.x-4.1.

Following several hours of debugging we've managed
to find that one of the following actions solves the issue:

1. Disabling the Omega 4 option: "Rebuild CSS and JS aggregates on every page load" which is part of its development extension.
OR
2. Disabling "Cache pages for anonymous users" - i.e. caching for anonymous users (which of course is not an option :))

I'd be happy to provide more info if needed.

Hi!

Please read the guidelines for using issue tags: https://drupal.org/node/1023102

Regarding the problem you are describing:

I'd suggest you disable the CSS rebuild feature from the development extension. I am lowering the priority of this issue to "minor" for now as I can't validate it atm. and it's only relevant in development mode (so doesn't affect live sites). Will take a closer look next week.
