exception value not html-escaped in exception view

[webograph@…]

when raising an exception whose exception value contains html metachars like "<", these are not properly escaped in the exception view.

example:

# Create your view here.
from myapp.models import mydbobject
function throwexc(request):
    raise Exception, mydbobject.objects.all()

gives you:

Exception at /throwexc/
[<foo>, <bar>]
Request Method: GET
Request URL: http://localhost:8000/throwexc/
Exception Type: Exception:
Exception Value: [, ]

([, ] having html source code [<foo>, <bar>])

The exception value is properly escaped in the trunk (tested at 6206).
