Description of problem:
After install bind10 and follow the instructions in
http://bind10.isc.org/docs/bind10-guide.html#quick-start-auth-dns

Via "dig", the dns seems not working, so I systemctl restart bind10, then the abrt popped out.

Version-Release number of selected component:
bind10-1.1.0-11.fc20
