managingMarker returns YES when having no objects

[michaeltyson]

What steps will reproduce the problem?

1. create a marker manager
2. create a marker
3. [markerManager managingMarker:marker] returns YES

What is the expected output? What do you see instead?
NO

What subversion release are you using? Does the behavior occur on the
simulator, a real iPhone/iPod Touch, or both?

0.5, simulator

funny enough if you change the code to:

/// \deprecated violates Objective-C naming rules

• (BOOL) managingMarker:(RMMarker*)marker
  {
  if (marker != nil && [[self getMarkers] containsObject:marker]) {
  return YES;
  }
  return NO;
  }

iso indexOfObject, it does work, though i cannot explain why...
