under KDE, gnome-keyring does not set environment variable

under KDE 5 in vivid, after installing gnome-keyring and libpam-gnome-keyring, the gnome-keyring daemon is running, but its socket directory is not exposed in a $GNOME_KEYRING_CONTROL environment variable, so applications that need the GNOME keyring cannot access it.

To workaround I've added the following to the .bash_profile , but its not really a long term solution:

    [ -z "$GNOME_KEYRING_CONTROL" ] && export GNOME_KEYRING_CONTROL=/run/user/$UID/keyring
