When an image shows up in "page not found" in Watchdog, how to find the content containing the image link? I disabled the countryicons_shiny module on my site, and now I'm getting some errors in Watchdog showing that the images weren't found:

I'm pretty sure this is a misconfigured view, but I have a ton of views and content types on my site, so I was hoping to find a way to identify the content (view, page, etc.) that is trying to display the icon.

I have all my views in features and I tried using grep countryicons * but no results are returned.

How can I find what content is linking to the image when I only have the watchdog log "page not found entry?
This is not the ultimate solution, but in this specific case, since I moved the icons into another module, to fix this particular error I just symlinked the folders:

mkdir countryicons_shiny
cd countryicons_shiny
ln -s ../mycustommodule/countryiconsdirectory images
