      ===
      I am using Calibre 2.2 (an ebook management system) which uses Qt 5.3.1 at an Ubuntu 14.04 system.

      I am using a KVM switch, some times, if i switch away from the Ubuntu system, Calibre crashed with a Segmentation fault (core dumped).
      I gave the developer a back trace and he said, it is a bug in Qt 5.3.1.
