Do understand bugzilla is not a support forum. But if that RWCString is the one, that's among first google results, you need to pass foo.data() instead of foo there.
@Martin if you use that software please try Rafał's suggestion in overlay. I tend to avoid fetch restricted pkgs.
Please try with consed-27 and reopen if still exists
