Sometimes after adding a MultiColumnPlugin the page containing it completely breaks and only throws ``` AttributeError at /en/home/ 'NoneType' object has no attribute 'get_plugin_class' ``` in https://github.com/divio/django-cms/blob/develop/cms/middleware/toolbar.py#L29 'instance' in this context comes from https://github.com/divio/django-cms/blob/develop/cms/models/pluginmodel.py#L171 where a "DoesNotExist" exception is raised and so instance = None. I tried to figure out how to fix it but I wasn't successful. The problem only seems to occur with MultiColumnPlugin - maybe it doesn't save something I think. Somebody who knows the code better should look after it. Unfortunately I don't know how to reproduce it - I just added a MultiColumn and it broke (using the cms from git in branch develop).
