Short description of error
When rendering a scene with combined render layer turned off Blender will still render the combined layer. Also I am get a crash when do thing will rendering with the combined render layer turned off mainly when switching render layer. Possible related when switching render layers during render I get this result:

Exact steps for others to reproduce the error

Render .blend Render_Layers_Bug.blend1

Several tries might be needed

Combined pass can't really be disabled in BI and Cycles, they'll be evaluated anyway. However, switching render layers during rendering shouldn't cause artifacts and crashes.

That seems confusing from the UI point of view, if someone unchecks the the check box they expect it not to render.

Other render engines might be using the option and currently we just don't have ability to distinguish such a render engines. Also in theory we can totally avoid Combined pass in BI, it already ignores most of the evaluation in there.. So surely there are things to improve here, but those aren't necessarily a bugs.

Ok, so for the combined pass itself i would not consider this a bug, just something we can look into improvements.

Crashes i was not able to reproduce, but i've just committed some fixes which solves deadlocks. So please grab build which will include commit d631252 and give it a test again. If there'll be issues with stability in that build, please make a new report with corresponding title, description and exact steps of how to reproduce the issue.

For now i don't really see anything else to be fixed here.
