See my SPM post on the same topic:

At least in my case, it's apparent that the desired behavior is for SPM to
just "no significant voxels." It crashes out with an error because it
tries to plot the global signal timecourse(s) (for a diagnostic), but for
my model there are none (the vectors are empty), which they should be.

Don't know about that.
