Heya Marcus,

I'm not really sure what I changed in the packaging that might have
caused this, but maybe I'm just too tired. :)

(Greeting to you too ;))

I'll probably do so in the second upload for 2.4.5, I'd like to push
2.4.5-1 in a few minutes/hours.

(I'll probably have udev things to change, looks like the maintainer
likes moving targets…)

Mraw,
KiBi.
