Did that with my black berry porter a couple months ago, it was fine at bottling. I'll let you know the final verdict next week when I try the first bottle.
The shopping bag trick works great. When I used it the stopper flew out accross the kitchen and my Neapolitan Mastiff caught it in the air, and started chewing on in like gum. Then I had to get the stopper out of the Neo, that was harder... That particular stopper was heading for the trash anyway, it was just a hair smaller than my other ones and had threatened to go through a couple times before it did.
