This seems to be a somewhat more general problem than just logging out
from KDE; see bug #660152, which I suspect is a duplicate of this.

Now the fun begins.

What appears to be happening is that FreeClientResources is being called
on the server pseudo-client, which is perfectly reasonable.  However, at
some the resource list stored in clientTable[0].resources has become
corrupted, and one or more of __GLXdrawables stored in there ends up
with garbage values.  When FreeClientResources hits this resource,
DrawableGone from glx/glxext.c is called on the corrupted __GLXdrawable
and explodes somewhere, either with a bogus pDraw or calling an invalid
->destroy().

I've traced through the resource code, and these __GLXdrawables are
perfectly valid when they're getting added to the resource list.
Furthermore, nothing from the resource code seems to be fiddling with
them; it looks like some unrelated code is *sometimes* scribbling over
*some of* the values in memory.
