I created a custom thumbnails for some of my feeds, but they don't appear in doggcatcher's notifications.
Here's a pic of how a notification is supposed to look: https://dl.dropboxusercontent.com/u/43910681/doggcatcher%20bug%202.png

Yup, I had a similar bug related to the thumbs on the lock screen, it's probably the same issue. I updated the bug and moved it up in the schedule a bit.

Thanks for reporting the problem.
I don't know if this helps, but I have a motorola droid bionic running 4.1.2
