Favicon for /rss.xml is Quotion logo, not mine

When I add my site feed to an RSS Reader (in this case, I am using

http://reederapp.com) it’s showing the Quotion ‘Q’ logo instead of my own.

I was a bit confused because the xml itself includes my site image in the channel description … but I think what might be happening is that Reeder is looking at the Favicon when it retrieves the RSS feed … If I open the URL for mine in Safari, I can see it’s the ‘Q’ icon.
