Adding --verbose to the gpgsm invocation may give you additional hints.
IIRC, "--debug x509" may be helpful to. Is file.sig a valid CMS file;
that is can you parse it with dumpasn1 or the openssl sub-command?
BTW, gpgsm has an option --assume-base64 so that you don't need the base64
tool.
Thank you very much for the additional information,
much appreciated!
Yes, file.sig can be parsed with dumpasn1.

Stefan
