Probably a duplicate of #230 which will be fixed with the next release.
(It seems to be pretty rare so maybe you can just try again and it won't crash)

Since there was no activity from the issuer or willingness to cooperate (by trying if this is present in the latest version (2.1.0B), this will be marked as solved and closed.
