Bug: Cannot Add to Render Queue without Audio

I need a 6 minute video with no audio. I can't Add to Render Queue.
As soon as I include any audio (in my case a completely silent fake clip) I can add and render.
Even is your render contains audio, it should just render blank audio if no audio clips are used. But it should let me render. Especially when I deselect audio from output.
Edit: Actually it still doesn't work if I delete the video that had blank audio and try to just use the audio. I have to have a video clip with audio to render it seems.
