RequireBackup not honored

Having two repositories like this:

<Repository name="sca6000">
<Module>/usr/lib/opencryptoki/libopencryptoki.so.0</Module>
<TokenLabel>dnssec</TokenLabel>
<PIN>dnssec:apa123456</PIN>
<Capacity>1000</Capacity>
<RequireBackup/>
</Repository>

<Repository name="smartcard">
<Module>/usr/lib/opensc-pkcs11.so</Module>
<TokenLabel>OpenSC Card (KSK PIN)</TokenLabel>
<PIN>1234</PIN>
<Capacity>1</Capacity>
</Repository>

The smartcard respository does not require backup. But ksmutil still reports that it needs backup:
