title: cocoa app crashes once in a while not reproduceable
body: <p>I sometimes get a strange error. I do the same thing several times and then sometimes the program just crashes. Most of the time it happens when I try to open a file Dialog or try to determine a random number. I have no idea what it could be. It would be great if someone could point me into the right direction.</p>
  
  <p>Here is the Log I get and an image:</p>

  <p>The following happened after the first answers by gaige and Joshua Nozzi:</p>
  
  <h2>------------------------------------------------------------------------------------------</h2>
  
  <p>I enabled Zombie Objects and when I ran it the first time it told me:</p>
  
  <blockquote>
    <p>Class _NSZombie_NSIBUserDefinedRuntimeAttributesConnector is
    implemented in both ?? and ??. One of the two will be used. Which one
    is undefined.</p>
  </blockquote>
  
  <p>and</p>
  
  <blockquote>
    <p>CoreAnimation: warning, deleted thread with uncommitted CATransaction;
    set CA_DEBUG_TRANSACTIONS=1 in environment to log backtraces.</p>
  </blockquote>
  
  <p>so I set CA_DEBUG_TRANSACTIONS=1. Could the second warning be because of me running the open dialog in a background thread?</p>
  
  <p>I ran it a few times now and I got several more errors but I can't really see what the problem is and why there isn't always the same error when I perform the same task. I don't expect anyone to actually go through all the error messages (they are more to illustrate my problem) but it would be great if someone could show how I can read and understand them (is there a good tutorial on that?):</p>
