Hi

Just updated everything to 1.1 and had this thrown at launch:
file not found base/graphics/technology/automation.png
I worked around by making a copy of another automation.png

I just checked all my up to date mods with Grep (it searches all defined files, I told it to search my entire Factorio mods folder. My copy of the mods aren't zipped, so I can edit them.)
There are no instances of base/graphics/technology/automation.png in any of my mods.

1. I seriously doubt the issue is with the mod you've reported the error to. This is the Library, it doesn't add any game content, it's just required by my other mods.
2. Are you sure you're using all up to date Bob's mods?
3. Are you sure the issue is even with Bob's mods?

Got the same error when the mod "Miles' Bob's Expansion" is installed. Probably related to this mod, I will report the bug there.
