-- Information about the crash:
- What I was doing when the application crashed: KMail and Google Chrome open - attempted to drag Chrome from Monitor 2 to Monitor 1. Running dual-head on NVidia GTX750 with proprietary drivers (installed from NVidia installer) version 384.69.

The same crash has occurred several times when the desktop is sitting completely idle.

The crash can be reproduced sometimes.
