commit e78a4bc9a921f597224af07def876ba18b8733c5
Author: Thomas Woerner <twoerner@redhat.com>

    Fix segmentation fault if used with the options -1 -C
    
    Curses is not used with the "-1" single option, but c_warn is used if
    counters are not enabled in the kernel and "-C" option is given.
    
    Fixes: RHBZ#599181
