Thunar crashes when viewing a folder that contains a certain image (when generating the thumbnails). Changing the file name makes no difference.

Reproducible: Always

Steps to Reproduce:
1. Save one of these pictures in a directory: http://launchpadlibrarian.net/6872702/asd.jpg ; http://launchpadlibrarian.net/8043398/hum.jpg
2. Launch thunar and go to the directory
3. Enjoy ^^"

Actual Results:  
Thunar freezes and finally crashes.

Expected Results:  
Thunar should diplay the thumbnails
