Sometimes GNOME keyring and libsecret fail to set up the right temporary keys
(https://bugzilla.gnome.org/show_bug.cgi?id=778357). This has been fixed
upstream, but still breaks with the distros used by the automated testing
occassionally.
Retrying the operations after disconnecting from the server is an attempt
to recover from this sporadic error.
