In OpenPGP, the choice for symmetric cipher is made by the key owner. For example, if you were encrypting a message to me, the symmetric ciphers that I am willing/able to accept are specified by my key. You, of course, are free to override this and use any cipher you want. The warning message means: "Hey, the message I just decrypted was encrypted using a cipher that isn't on my list of allowable ciphers." In your case, you've encrypted the message using Rijndael, but the key doesn't have Rijndael as an allowable cipher, so it's warning you.
