I've only seen one other report of this so far, and accidentally encountered it today in the Imperial City. Currently you have the option to instantly (minus w/e re spawn delay there is) revive in the IC by attempting to revive at one of your alliance controlled keeps in Cyrodiil. The link below is to recorded game play showing the bug.

I've also submitted a bug report through the in game client ticket # 170602-003091.

I haven't found anyone exploiting this yet, and hopefully it can be fixed before this happens.
