  While testing Qt 5 support on Ubuntu, and validating the support for
  OpenGL ES2.0 with Pandaboard, I couldn't start Snowshoe (Qt 5 - webkit
  based browser) as it gives a segmentation fault and also breaks the X11
  server (with the pvr driver).
  
  After a quick check with Snowball (Mali 400), it worked properly and as
  expected, so this could probably be related with the current SGX driver
  available for Pandaboard.
  
  How to reproduce the issue:
  1) Enable https://launchpad.net/~canonical-qt5-edgers/+archive/qt5-daily
  2) Install 'snowshoe-mobile' package
  3) Run snowshoe: $ PATH=/opt/qt5/bin:$PATH; snowshoe
  
  This is with Ubuntu 12.04 with pvr-omap4 1.7.10.0.1.21-0ubuntu1 (from
  archive) and also 1.7.15.0.1.57-1 from TI's PPA.
