Using instructions found in Debian bug report:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=804340

This looks like a database issue to me, however the reporter of the Debian bug thinks it is something to do with the capital-letter-named django application. Which seems weird to me.

A search for similar bugs found #17998 - not idea if this is related or not.
