According to the PetSmart website, here are the facts on the food. I have highlighted the potentially dangerous ingredients in red and questionable ingredients in blue.

Something that really concerns me about this food is the appearance of leeks, especially so high in the ingredient list. Rabbits should not be fed any members of the onion family, so this could be potentially dangerous.
Alfalfa is not recommended in the diet of an adult rabbit because it is very rich and can lead to weight issues. Peas, oats, and Beet pulp are fillers and provide almost no nutrition, but are very starchy and can lead to intestinal problems. Salt and Molasses are unnecessary taste additives which could be dangerous in large amounts.

As far as the analysis, this food is ok. The fiber is nice and high (although this is the minimum so there could be less. The protein might be a tad bit high.
Just like you stated in your post, feeding rabbits on Muesli-type mixes is not generally recommended because often rabbits will pick out their favorite parts which will lead to an unbalanced diet. Many of these mixes also contain unnecessary sugary bits to make the food more appetizing to your rabbit and visually. Another danger of this food is the potential chocking hazard on the inconsistent sized pieces.
Overall, while this food is definitely one of the better mueslis on the market, I would recommend you switch to a pellet. Here, we generally recommend any of the Oxbow rabbit pellet line.
