Drag and drop images or video into subfolder will prevent folder from loading.

From the Launchpad report: https://bugs.launchpad.net/ubuntu/+bug/454297 "When I drag a picture on a folder, if I go to this folder, I don't see the image thumbnail and the mouse is busy. I don't see the thumbnail files until I kill nautilus. Thumbnail preview must be enable. The bug occurred on both of my computer. Same thing happened with videos" There is a video demonstrating the behavior in the bug report
Please have a look at the video attached in the Launchpad's bug report. It perfectly illustrates the problem. Same problem manifest itself for PDF and video files, so I would guess it is a general problem with thumbnails generation blocking nautilus forever (i.e. not only while the thumbnail is generated)
Here is the direct link to the video showing the bug: http://launchpadlibrarian.net/33915069/test-0000.mpeg
Some more information - After this bug is triggered and a folder view is missing files, if you then switch to another folder with missing thumbnails, then back to the first folder, all the missing files are displayed again with proper thumbnails.
Fixed by commit e487552287e5970dbbb39199b55026f2788bb42b on master and cherry-picked to gnome-2-28.
