Hmm the traceback doesn't really indicate much to me, let me know if you can
reproduce this consistently.
I simply clicked on one of the corners inside the grid and dragged

Actually, the next thing I'll be working on is to try and make
background threads generate thumbnails, so it shouldn't be that
bad. But indeed something to consider.
If you have 100,000 photos and every one of them has to be
re-thumbnailed? Even if it's done incrementally, at least until the
thumbnails are recreated they're going to have to get built on the
fly, which is very slow.

Well actually, that was one of the things I threw out (see my
blog), it took quite some time to do this scaling.
Even a fast resampling (not rescaling)?
