New description:
I'm writing very simple code while learning Django. I noticed there is
some error in the server console window sometimes when I refreshed my
browser.
The error always ends with the line in the ticket Summary. The following
is the entire copy of the error.
What the strange is everything works good except the error information.
Nothing is broken. The view is always rendered properly. Also, this error
doesn't always happen. It occurs occasionally. Any idea what it is mean?
