Bug 1268217

Description of problem:
As a part of building of custom rpm package as described here:
https://access.redhat.com/documentation/en-US/Red_Hat_Network_Satellite/5.3/html/Deployment_Guide/satops-rpm-building.html
I was trying to generate a gpg key for signing the package.
However the command `gpg --gen-key` keeps failing at the point of passphrase request: it says "gpg: cancelled by user".

Version-Release number of selected component (if applicable):
$ cat /etc/redhat-release 
Red Hat Enterprise Linux Server release 7.2 Beta (Maipo)

$ rpm -q --whatprovides `which gpg`
gnupg2-2.0.22-3.el7.x86_64

How reproducible:
Always

Steps to Reproduce:
1. gpg --gen-key

Actual results:

$ gpg --gen-key
