An app thats previously worked fine has started raising "Bad Request(400)" in my app whenever using the filebrowser app. The app is set to DEBUG=True, errors elsewhere raise the expected yellow screen of doom. Diffing the settings from an older revision tells me nothing has changed there and the file settings point to correct directories which I believe rules out Django FileBrowser 400 Error as an explaination. This certainly used to work. The problem is neither the console or the error dump page which works elsewhere in my install appears , just the terse Bad Request page.
I grant this isn't enough information to debug the error itself, and frankly I don't know where to look.
Rather my question is;- when this happens, is there a way to trap it at the point it raises 400 and debug it. I use ipdb in other circumstances when I need to examine the program state, but this isn't even giving me enough information to know where to drop a breakpoint!

To avoid confusion, Debug is set to True, logging is configured to dump to console and all console shows is
