Admin page clear theme registry causes omega's registry hooks not to fire [#2343745]

Problem/Motivation

Still debugging this issue but I thought I'd send out what I know so far.

Clearing theme-registry from the CLI or the front end theme has no problem(and fixes the registry).
Clearing the theme-registry from an admin themed page, doesn't fire omega's theme registry hooks and breaks the site as all the theme/ preprocess/ and other nice folders don't get searched and cached in the registry on the rebuild.

This happens on all 3 servers: dev (PHP 5.5 + redis), stage (PHP 5.3), live (PHP 5.5 + redis + zend opcode).

For some reason this doesn't happen on another developers server who uses MAMP PHP 5.4.

I'm not sure if it's a caching issue though turning off redis and opcode didn't solve the issue.

This could be possibly a core bug... need to get deep in the debugger to solve this.

Admin theme is adminimal_theme btw.

I've seen this issue before but we added a fix for that quite a while ago. It indeed sounds like a core bug as hook_theme_registry_alter() should *always* be executed for the theme that it affects. Normally, the theme registry should only ever be built for the active theme. The functions in question (_theme_build_registry()) are marked as private (leading underscore) and should only be invoked from theme_get_registry() which purposely only works on the active theme. You should check your modules on that page for any code that invokes these functions outside of these rules.
