Unfortunately the backtrace is lacking debug symbols. If you are able to reproduce please install the debug packages provided by your distribution (please ask the distribution support channel on how to install them) and attach a new backtrace. From what we see it's a crash in the proprietary nvidia driver triggered somehow through the aurorae window decoration. As a workaround switch to the breeze window decoration.
