Maybe not a bug, just and inaccessible sprite.
The sprite for automation science technology is not available via the rich text ([technology=automation-science-pack]). While this is logical as there is no technology for the automation science packs, the sprite exists as \data\base\graphics\technology\automation-science-pack.png; it's just inaccessible.
Technology icons differ from the actual science pack icons ([technology=_____-science-pack] vs [item=_____-science-pack]) and there are both sprites available for all but this one science.

Thanks for the report. Because there's no technology you can't use the technology rich text icon. That's how that works and isn't a bug.
