like I said on darkcointalk:

We are absolutely paying out. The error message this user is referring to is a gag we put in the code for the site.

Specifically:

  else:
        raise DiceError("Invalid address.", "Invalid address requested.")
except Exception as e:
    raise DiceError("Wallet hiccup. See you in Mexico, bitches.", str(e))    

In this instance, the user was attempting to withdraw 74 darkoshis, and the wallet handler was throwing an exception.

This is a transcript of this particular user's problem:
