Django sorl.thumbnail issues

Can't seem to get sorl.thumnail to create thumbnails. It just creates empty files.

Say, tried uploading 3.gif, the original file gets uploaded fine, thumbnail does not created, it creates a file with 0 bytes:

-rwxrwxrwx 1 www-data www-data 14128 2010-02-13 06:57 3.gif
-rwxrwxrwx 1 www-data ww开发者_如何学运维w-data     0 2010-02-13 06:57 3_gif_200x200_autocrop_q85.jpg

The template looks like this

{% thumbnail photo.photo 200x200 autocrop as thumb %}
<img src="{{ thumb }}" width="{{ thumb.width }}" height="{{ thumb.height }}" alt="{{ photo.title }}" />

Had to reinstall PIL
