Warning with Check MK 1.6.0

[marbaa]

During service inventory this warning occurs and no check is added:

WARNING: Exception in discovery function of check type 'qemu': The discovery function "inventory_qemu" of the check "qemu" is expected to take a single argument (info or parsed), but it's taking the following arguments: ['checkname', 'info']. You will have to change the arguments of the discovery function to make it compatible with this Checkmk version.

I've modified def inventory_qemu(checkname, info): to def inventory_qemu(info): and then it works.
