This was already discussed in bug 148799. The point was that my code should only write out a string, yet it somehow seems to be calling the page since it loads the favicon from it. However, I am having trouble reproducing the issue on my home PC, but I have an older build. Will need to investigate more...
This might be a dup of bug 109672, "site icon for iframe content is shown as proxy icon".
I can't reproduce this anymore.
