KWin sometimes gets into a mode when it always crashes on start if desktop effects are enabled. This happens on Haswell hardware.

Huh, I've never seen this failure mode. But it sounds entirely plausible.

The X server's GLX code has a bug where it may randomly return a bogus visual/fbconfig; perhaps it ended up not having stencil, and we crashed?

That bug is fixed in X server git, and the upcoming 1.15.1 and 1.14.6 releases (due any day now). Alternatively, you could try asking KWin to use EGL:

   KWIN_OPENGL_INTERFACE=egl kwin --replace &

Does either of those fix this issue for you?
