ronaldmik@gmail.com, Ubuntu 13.04 reached EOL on January 27, 2014. For more on this, please see https://wiki.ubuntu.com/Releases.

If this is reproducible with a supported release, it will help immensely if you filed a new report with Ubuntu by ensuring you have the package xdiagnose installed, and that you click the Yes button for attaching additional debugging information running the following from a terminal:
