Somehow, you have overwritten the 'info' attribute of the
django.messages module with a string, and so it blows up.

Look for places where you assign to anything named 'info':

ack "\Winfo.*="
ack "setattr\([^,]*,.*info"

or

grep -r "[^a-z_]info.*=" *
grep -r "setattr([^,]*,.*info" *

I know you said not to blame your custom middleware, but this does not
happen with stock 1.4.2, so if you have this happening even in
requests that do not touch your views, it most likely will be your
middleware.

It would be easy to test if you can reliably reproduce this in the
admin site, simply disable the custom middleware and see if you can
still reproduce the error.
