can you 1st turn on debug logs (menu/system/logs/settings ...... save somewhere reliable not flash!!), reboot (it should ask but if not reboot) and then try this and let me know the result. (again copy to /usr/lib/enigma2/python/Plugins/SystemPlugins/ViX).
You may see a message displayed on screen
Assuming it doesn't crash let me have debug log (post here)
