user's profile information not displayed in "Agreement accepted by ..." message

When a user views a contract that he already accepted, there appears a box saying "Agreement accepted by !firstName !lastName for !company on !date" (by default). The placeholder variables are substituted in role_contracts_view() by the values of profile_* attributed of a global $user object. However, in my case, this $user object does not actually carry these attributes, but only the $cUser object loaded by user_load() in the same function. Replacing $user by $cUser as in the attached patch fixes the problem.
