Problems with sliderInput in R Shiny - Getting NaNs

Question

I am trying to make a slider tab that has years between 2005 and 2040. It seems pretty simple, right? It usually works fine, but from time to time I move the slider too far to the left, and that gives me NaN, which usually breaks things up. I tried to tweak the rest of my code so that it didn't have a problem, but it still eavesdropped on me. I have calculated the Internet for an explanation, but so far nothing. Here is my ui.R:

library(shiny)

shinyUI(fluidPage(
  titlePanel("Test"),

  sidebarLayout(
  sidebarPanel(

    selectInput("over", "Indicator", c("Indicator 1", "Indicator 2"), selected="Trade"),

    selectInput("type", "Type", c("Discrete", "Continuous")),


    # Nothing particularly unusual here...   
    sliderInput("year", "Year", min=2005, max=2040, value=2005, animate=animationOptions(interval=1500), sep=""),

    checkboxInput("table", "Show Table")

    , width=3),

  mainPanel(    
    uiOutput("plot"),

    uiOutput("showtable")

    , width=9)
  )
))
