This is getting really strange.. first I was testing to see if the issue happens when Rhythmbox goes from track to track. The album covers showed up the way the should. But then, after the first 5 tracks or so, covers disappeared from the notifications again. After that I couldn't get it working anymore, neither when I switched tracks manually.
I restarted Rhythmbox to see if that changes anything, but the issue remained. Then I rebooted the whole system, but still no album covers. Playing the same tracks which showed covers earlier don't show covers in the notifications anymore either, so it's not the mp3 files that are causing this.
