Nautilus: 100% CPU-Usage after login

[John Doe]

Binary package hint: nautilus

As said in the Summary. I'm using Intrepid A6, after todays updates, Nautilus is using nearly 100% of CPU-Time, leading to an extreme choppy Desktop-Performance. It seems as if Nautilus is working heavy on the Images in "/home/USER/.tumbmails" Folder. When deleting the Folder, CPU-Usage turns back to "normal" Range, but some Menu still reacting very slow.

Updates installed before that behaivior starts:

gtk2-engines-pixbuf (2.14.1-0ubuntu1) to 2.14.2-0ubuntu1
libgtk2.0-0 (2.14.1-0ubuntu1) to 2.14.2-0ubuntu1

I'm getting the same problem as this, being caused by the .thumbnails folder. I've got thousands of images archived for storage and recently extracted them. This caused nautilus to use up 100% cpu even when all folders are closed. The only thing I can do is delete .thumbnails and nautilus behaves again.

Is there a setting somewhere to stop it generating thumbnails when I don't want it to?
