[Paraview] Paraview 3.8.0 crash in Edit Color Map

[Cihan Altinay]

Hi list,

I just compiled Paraview 3.8.0 RC2 and found a reproducible crash 
whenever I click on "Edit Color Map".
Version 3.6.2 compiled with exactly the same dependencies (mesa, mpi, 
qt) does not exhibit this crash.

Configuration details:
Linux 2.6.27.45-0.1 SMP x86_64
Qt 4.6.2, Mesa 7.8.1, MPT 2.00
Mesa built with off-screen support

I created the stack trace below and found this suspicious value:
(gdb) print ctx->DrawBuffer
$2 = (GLframebuffer *) 0xefefef00efefef

Stack trace:

Program received signal SIGSEGV, Segmentation fault.
