Still having this RGWLC crash once a day or so. I do plan to update to
Luminous as soon as that is final, but it's possible this issue will
still occur, so i was hoping one of the devs could take a look at it.
My original suspicion was that it happens when lifecycle processing at
the same time that the morning log rotation occurs, but i am not certain
about that, so perhaps the bug title should be updated to remove that
conclusion. (i can't edit it)

Here, this (the RGWGC, or store->gc) is NULL, so that's the problem. I
have no idea how the store isn't initialized, though.
