How reproducible:
Always

Steps to Reproduce:
1. have more kernels installed
2. # rpm -qa | grep kernel-3.*$ | grep -v kernel-3.8.3 | xargs dnf remove
2. kaboom
  
Actual results:
crashes

Expected results:
As YUM - i.e. doesn't run the operation.

Additional info:
This runs as expected when:
# rpm -qa | grep kernel-3.*$ | grep -v kernel-3.8.3 | xargs dnf remove -y
