Thanks Joe! From

svn_swig_rb_to_depth(VALUE value)
  if (NIL_P(value)) {
    return svn_depth_infinity;
  } else if (value == Qtrue) {
  } else if (value == Qfalse) {
  } else if (RTEST(rb_obj_is_kind_of(value, rb_cString)) ||
             RTEST(rb_obj_is_kind_of(value, rb_cSymbol))) {
    value = rb_funcall(value, id_to_s, 0);
    return svn_depth_from_word(StringValueCStr(value));
  } else if (RTEST(rb_obj_is_kind_of(value, rb_cInteger))) {
    return NUM2INT(value);
  } else {
             "'%s' must be DEPTH_STRING (e.g. \"infinity\" or :infinity) "
             "or Svn::Core::DEPTH_*",

This seems to fall victim to issue #2951, [sparse-directories] Fix
non-recursive mode of compat APIs to use depth empty instead of files.

Also, it defaults some APIs (e.g. client.proplist) to
svn_depth_infinity, when I'd more intuitively expect them to use depth
empty (as per their behavior from the command-line client).
