CKEditor is incompatible with Installation profiles.

CKEditior breaks installation process in an installation profile. The reason is the use of module_load_include in the hook_requirements implementation of the .install file. System table is not, yet, available when hook_requirements is invoked by an installation profile which breaks module_load_include, which breaks entire installation profile with a violent error.

I am attaching a patch that does a minor change to code: moves module_load_includes under existing:

if ($phase == 'runtime') { .. }

check, since the only code in the hook_requirements implementation is within that "if" statement and you don't need inclusion outside that statement anyway.

This fixes the problem with installation profiles.

As a side note, if I may express my opinion, you should not be using module_load_include for files that belong to the same module. A call like:

require_once (dirname(__FILE__) . '/ckeditor.module');

is both more reliable (would not have given you an error in installation profile) and faster too (since it does not involve a DB lookup).

You only need module_load_include if you are loading files from other modules.
