Comment:
For the sake of google indexing, here's the whole error which I could
prompt by moving the folder '/usr/local/share/proj' to a new spot on the
filesystem such that postgis can no longer find it.
This error happens on page reload of a previously saved record in the
admin. Again, this is '''not''' a GeoDjango problem but I do think
GeoDjango could provide better error handling and reporting.
