10401	Very long URL cause django error.	bigmonkey.bigmonkey@…	nobody	"I have configed the right handler404 for pages mismatching all the regular expressions in urls.py and it often worked fine.

However when I entered a very long URLs with characters more than 250, the folloing error information would be listed:
======================================================

======================================================

The above exception should be handled and be taken by handler404.

Moreover, I test www.djangoproject.com, when I checked http://www.djangoproject.com/ladjflkjlkjlk, it gave me the right 404 page.
