Version-Release number of selected component (if applicable): 3.1.16


How reproducible:
When trying to connect to a RHEV instance using gnutls-cli, I'm getting the warnings below from valgrind. The RHEV instance is unfortunately only available on an internal network. I'm using gnutls-3.1.11-1.fc19
