This bug is still present in up to date 13.10 and 14.04. The issue is not icon previews since the same slow down occurs with small text/bin files. Given that many people have large collections of media files thisbug is a deal breaker for even casual users. It's a disaster in any kind of enterprise situation with large volume data. The problem is so bad that thunar has become part of my default install image.
