epiphany fails to open

[kardan]

Dear mainainers,

epiphany (3.4.2-2.1) fails with
> Gkr-Message: secret service operation failed:
> The name org.freedesktop.secrets was not provided by any .service
> files
> Ungültiger Maschinenbefehl

There was no information on this error message on the web, but I found
that the experimental version requires libsecret-1-dev and tried to
install it.
