Is this because of a |DCHECK(BrowserThread::CurrentlyOn(BrowserThread::UI))|
somewhere? If so, maybe we should think about making the class in question
derive from NonThreadSafe, which uses native thread identifiers instead of
BrowserThread IDs.

Sorry I forgot to add my reply. Yeah I agree. We should get rid of this. This is
true for other content_settings_providers as well. So I'd prefer to have a
sparate CL for that and fix all. Added a TODO.
