[Wien] segmentation fault error for beta-cristobalite

Dear Dr. Andersen,
The calculation does not work with 1 k-point. I should
mention also that this is a spin-polarized
calculation. The idea of a memory problem had occurred
to me, but I was not sure how correct it would be,
given that alpha-quartz ran successfully.
Beta-cristobalite should not be much more complicated
than a-quartz, I would think. I will double-check the
shell limits. 

And to Jorissen Kevin: Unfortunately, my computer
seems to be having some difficult with your MIME
message. Could you please reformat your response and
resend it?

The structure file is again included below.
Sincerely,

Dear Mr. Abrahamson,

if you have ensured that the shell limits are removed,
try add some swap 
space - you might be running out of memory. Does it
work with 1 (one) 
k-point?

Best regards,
Torsten Andersen.
