Granted, I have been only using Lion since it was released a few days ago, but I have not had that problem yet. Try filing a bug report. Apple should get it fixed if it persists.
Haven't seen it happen to me, are u sure u didn't add bookmarks with no letters but still accidentally didn't hold down he space bar, and then moving the invisible bookmark into the center? Lol, I doubt u did that, but still check.
