Short description of error
Set that atribute and crash on render

Exact steps for others to reproduce the error

2-try render (it should crash)
3-open again
4-change velocity to color or density
5-render (now shouldn't crash on render)

The crash is due to an arithmetic exception thrown in the image interpolation code:

Program received signal SIGFPE, Arithmetic exception.

0x00000000032b46d1 in wrap_periodic (width=0, x=-1, this=<optimized out>)
    at /home/kevin/src/blender-git/blender/intern/cycles/kernel/./kernel_compat_cpu.h:113
113			x %= width;

Now the things is that only 'color', 'heat' and 'density' attributes/fields are supported in Cycles, but for some reason the 'velocity' attribute is still added and it crashes due to uninitialized data (would expect to have a nice pink/magenta volume instead, as for missing textures or images).
