Thanks, I will add that and check it stops the cras crash - crashing the
entirety of plasma is always bad :)

Googlign suggets (and Matias seems to confirm :) that this is due to a
lack of OpenGL context, but I don't really know how to fix this (damn
being taugh OpenGL at uni by a lecturer who didn't have a clue about it
either!). Maybe Plasma::GLApplet should create a context by default, or
provide a way of querying GL version/capabilities?

Thanks.
