    plparse: Fix invalid check of non-dereferenced pointer against NULL
    
    g_strsplit() guarantees to return a non-empty array. line is set to
    lines+1, so can never be equal to 0 (i.e. NULL). It needs to be
    dereferenced first to check for the array delimiter.
    
    Coverity issue: #60477
