I've had this issue now several times. I am running LR 1.1 on a MacBook.
During the last months, I had this import problem almost every time I got the pictures off my card (which was in my camera). I didn't pay much attention to it because I thought that maybe the problem was a corrupt file.
But last week it imported only 3 out of 20 files and that concerned me. If I start up LR, connect my camera it takes forever to recognize the camera (this is a recent phenomenon, it usually took no more than 5-10 seconds, now about 2 mins) and then it only shows me a certain number of pictures and others are just plain grey boxes.
I close the import dialog, click on IMPORT in the Grid View and then it works. It bothers me quite a bit and I hope there will be a fix soon.
