kmymoney2 (in Extras) can use this, but only if aqbanking is built --with-frontends= that includes kbanking.
Hold for now, pending a query to kmymoney2's devs as to whether enabling it's kbanking support is advisable or not.
Turns out I won't want/need to enable kbanking in kmymoney2 in the near future, but it's still something worth consideration to enable here in aqbanking when/if you ever find copious amounts of free time. (:
Fixed in currently-in-review package. See bug 222522.
Fixed in 2.1.0-14.
