``````

When execute this code:
```from sorl.thumbnail import get_thumbnail; im = get_thumbnail('/home/user/webapps/myproj/yourpics/media/users/user/images/after rain.jpg', '32x43')```
``````


Any idea why?

When i commented line 236 `del self.tagdata[tag]` in file `PIL/TiffImagePlugin.py` error disappeared.

OK…
