setting the url field of a OpenPGP fails when using gpg-agent

[Michael Bienia]

Hello,

if I try to set the url field of an OpenPGP card using gpg with
gpg-agent it fails with the following error:
| gpg: sending command `SCD SETATTR' to agent failed: ec=6.32769
| gpg: error setting URL: general error
But I can set an url if I use gpg without gpg-agent.
