sorl-thumbnail not working

I have been trying for several hours now to get sorl-thumbnail working, but it just won't work.

The hard part is that it's not showing errors so I have no idea whats wrong. I followed the instructions to install it.

My full code can be found here: https://github.com/samos123/Samos-IT/tree/master/samosit

template: https://github.com/samos123/Samos-IT/blob/master/samosit/templates/projects/project_detail.html

{% load thumbnail %}
{% thumbnail object.image "100x100" crop="center" as im %}
    
{% endthumbnail %}

view: https://github.com/samos123/Samos-IT/blob/master/samosit/projects/views.py

def detail(request, project_id, slug):
project = get_object_or_404(Project, pk=project_id)
imageurl = "/media/"+project.image.url
return render_to_response('projects/project_detail.html', {'object' : project, 'imageurl' : imageurl}, context_instance=RequestContext(request))

Thanks to sorl I can now finally see what the problem is. This seems to be the error: See the full error here: http://pastebin.com/0Yddt10N
