map wants a procedure as its first arg and a list as its second arg.
Your problem is that gnc:account-get-children doesn't return a list.
Under the hood, it maps to a C function which returns a vector, and
that return value is mapped to a special Scheme type called a
'pointer-array'. You need to use the function 'pointer-array-ref'
(similar to vector-ref) to get access to an element.
Good luck!
