Bug#977101: knot: duplicate zones, segfault when generating new DNSSEC keys

[Gedalya]

Hi Jan,

For some reason I didn't get your message via email, but saw it when looking at 
the Debian bug.

I see a fix for this in 3.0.4 (89c9a233). When that's packaged I'll try to 
confirm that this is fixed.

Thank you!
