Building current master on Kubuntu 15.04

[Michael Abrahams]

Hi Wolthera - could you share backtraces of any new OpenGL crashes in
Phab?  The crashes seem pretty system-dependent, it's hard to identify
the problems since I've squashed most of them on my own machine.
Release / debug builds also provide different points of failure.
