So, the relevant madness appears to be:
…snip all the glib detritus…
==30400== Invalid read of size 8
==30400==at 0xE8587FB: QGLXContext::makeCurrent(QPlatformSurface*)
(qglxintegration.cpp:333)
==30400==by 0x6339772: QOpenGLContext::makeCurrent(QSurface*)
(qopenglcontext.cpp:812)
So, it looks like there's a race between the destruction of an
QXcbScreen in response to a RANDR event in handleXcbEvent and (a) expose
handling and (b) some timer. I'll forward this upstream and might let
someone more familiar with Qt take over.

This problem exists since updating from ubuntu 12.04 to 14.04. It may

For completeness sake, here's mine on Latitude D630 (Intel 965GM

It seems display driver is not important, I always hit this bug it
seems, on nvidia, nouveau, radeon and intel.

I think it only depends on whether opengl acceleration is enabled
whether you get the former or latter behavior.
