We are sorry that we do not always have the capacity to review all reported bugs in a timely manner. You reported this bug some time ago and there have been many changes in Ubuntu since that time.

Ubuntu 12.04 (precise) reached end-of-life on April 28, 2017.

Do you still see a problem related to the one that you reported in a currently supported version of Ubuntu? See this document for currently supported Ubuntu releases:

https://wiki.ubuntu.com/Releases

Please let us know if you do otherwise this bug report can be left to expire in approximately 60 days time.

Thank you for helping make Ubuntu better.
