Thank you for reporting this. There is actually a bug. a,b,c etc
parameters are not working with k-points labels, so if you switch to
a,b,c you have also to write the k points coordinates of the path to
plot the bands, substituting:

   L 20
   gG 20
X 0
   1.0 1.0 0.0 30
   gG  1

with
0.5 0.5 0.5 20
0.0 0.0 0.0 20
1.0 0.0 0.0 0
1.0 1.0 0.0 30
0.0 0.0 0.0 1

HTH,

Andrea
