I'm not really familiar with the code but I'd guess that to fix that you would need to add to dealloc in PSMTabBarCell:

[self removeTrackingRect:_closeButtonTrackingTag];
[self removeTrackingRect:_cellTrackingTag];

But I don't really see where it's the tracking rect is being added at first glance.
