Don't know if this will help, but I found this error in my logs, and
it was caused by changing an image tag in a layout template, and
calling an image with a tal:replace incorrectly. From the history:

- <img tal:replace="path: here/globals/powered_by.png/absolute_url"
+<img tal:replace="here/globals/powered_by.png"
  tal:attributes="alt string:Silva site"
/>
