TemplateSyntaxError at /filebrowser/browse/ "adminmedia" is not a valid tag library: Template library adminmedia not found
Unfortunately django-filebrowser-no-grappelli is currently not compatible with Django 1.5.*
Solved by installing another package
pip install -e git+git://github.com/smacker/django-filebrowser-no-grappelli.git#egg=django-filebrowser
