There are a few problems with this:

You need to amend the definition of the method in lily-guile.hh, since
it's also used directly in the C++ code, with no optional arguments:

53 SCM ly_assoc_get (SCM key, SCM alist, SCM def);

+    programming_error ("Cannot find key ~S in alist, setting to ~S.",
ly_scm2string (key), ly_scm2string (default_value));

I think what Carl is getting at here is that you can't pass these
string values using format with programming_error () without adding
the macro `(_f', but this shouldn't be used in this case since it
internationalizes the message.

There's a bigger problem here though, since it's not clear what the
value of the key is going to be before converting it: ly_scm2string
will only work if the scheme value is a string.  This naturally
applies to default_value too, which could conceivably be any scheme
object.
