Seperate RSA subkeys for decryption and signing or one for both?

[Hauke Laging]

Hello,

are there arguments for preferring either

a) having one RSA subkey for decryption only and one for signing only

or

b) having only one RSA subkey for both decryption and signing?

Do any problems arise with the smartcard if the same key shall do different 
tasks?
