This is an automated message, with ID "auto-resolve01".

This bug has had no comments for a long time. Statistically, we have found that

highly unlikely to be the source of a fix to the code.

While your input is very important to us, our resources are limited and so we
are asking for your help in focussing our efforts. If you can still reproduce
this problem in the latest version of the product (see below for how to obtain a
copy) or, for feature requests, if it's not present in the latest version and
you still believe we should implement it, please visit the URL of this bug
(given at the top of this mail) and add a comment to that effect, giving more
reproduction information if you have it.

If it is not a problem any longer, you need take no action. If this bug is not
changed in any way in the next two weeks, it will be automatically resolved.

Patch v1.0

We already do:
http://lxr.mozilla.org/seamonkey/source/modules/libpr0n/src/imgLoader.cpp#776

That doesn't help when loading the URL directly though.

Does that mean that no changes are needed there?
