Thanks sir Oleg Rubel, 
I alraedy run the command
 "x lapw1 -band". 
And after that i edited the 
edit.case.insp
 and after that when i run the 
x spaghetti
 so i get this 
Commandline: x spaghetti -c
Program input is: "" 


number of k-points read in case.vector=         251
forrtl: severe (174): SIGSEGV, segmentation fault occurred
0.279u 0.069s 0:00.51 64.7%	0+0k 0+0io 12pf+0w
error: command   /home/azam/WIEN2k111-lopw/spaghetti spaghetti.def   failed

Did you run "x lapw1 -band" before? If not, the reason can be a mismatch between your k-list and the vector file.

I do not want to discourage you, but the band structure for large sells (supercells) does not look very pretty. The density of states (especially PDOS) can be more informative.
