title: caught segfault error in R
body: <p>I am getting a <code>caught segfault</code> error every time I try to run any plotting functions from the <code>ggplot2</code> package (1.0.0).  I have tried this with <code>qplot</code>, <code>geom_dotplot</code>, <code>geom_histogram</code>, etc. Data from the package (e.g. <code>diamonds</code> or <code>economics</code>) work just fine.</p>
  
  <p>I am operating on Mac OS 10.9.4 (the latest version) and on R 3.1.1 (also the latest version).  I get the same error with the standard R GUI, RStudio, and when using R from the command line.  The command brings up the default graphic device (Quartz for R GUI and command line), but also the terminal error.</p>
  
  <pre><code>library(ggplot2)
  qplot(1:10)
  </code></pre>
  
  <p>gives me the error:</p>
  
  <pre><code>*** caught segfault ***

  <p>I've gathered from others that this is a memory issue of some sort, but this error occurs even when I have over 2 GB of free RAM.  I know this is a widely used package, so of course this doesn't happen for everyone, but why is it happening for me?  Does anyone know what I can do to fix this problem?</p>
