Thank you for reporting this bug to Ubuntu. Ubuntu 12.04 LTS reached End of Life in April. See this document for currently supported Ubuntu releases: https://wiki.ubuntu.com/Releases

Please upgrade to Ubuntu 16.04 LTS and re-test. If the bug is still reproducible, increase the verbosity of the steps to recreate it so we can try again.

I apologize that we are not always to respond to bug reports promptly. Do feel free to report any other bugs you may find.
