This bug has an additional side effect, which is that if your minecart is destroyed with you in it, it will drop you underneath the track, possibly dropping you into a cave or lava ocean. This happens with any mob riding in a minecart which is destroyed by various means, including ghast and blaze fireballs.
I've had a couple of incidents riding on my nether rail when a blaze or ghast shot my minecart out from under me, and the minecart was safe and sound on top of the track, but I got dropped into the lava underneath the track.
