Wonder if this has been broken for a long time?

Only one bug of possible interest, but it doesn't look related now does it? Lucas?

I'm noticing Error: "TypeError: this._article is null" {file: "chrome://browser/content/aboutReader.js" line: 556}] in the logcat
I'm not able to reproduce this (at least I just tried on trunk). E.g, visit, enter Reader Mode, tap the 'fork us on Github' link, hit back. On back, I am re-entered back into Reader Mode.

Tested this w/Nightly (03/12) on my Galaxy SIV (Android 4.4.2)
I can repro it in || page, but not in others.

It works on the way in, which is odd... 
I've got a log if it'll help
