title: Nasty NSPropertyListSerialization Leak
body: <pre><code>NSString *anError = nil;
   id plist;
   plist = [NSPropertyListSerialization propertyListFromData:rawCourseArray mutabilityOption:NSPropertyListImmutable format:&amp;format errorDescription:&amp;anError];
   if (anError != nil){
  
    [anError release];
   }
  </code></pre>
  
  <p>The above code causes a memory leak every time I call it.  I am releasing the error but still there is a leak.  I haven't seen any resolution to this issue.  I posted this already and most respond that this is not a leak.  But see here in the leak performance tool:</p>

  <p>I need this fixed because eventually my app crashes.  Any ideas?  Many thanks</p>
