[gtk-osx-users] Memory leaks after toplevel window is destroyed

[Andrius <andriusr yahoo com>]

Hi all,
Working on Bluefish port to OSX, using gtk+3.6.4, gtk-mac-integration 2.0.1 on MacOSX 10.8.4. I

When using gtk-osx, I noticed that after toplevel window is created with menubar and then destroyed, leaks 
shows large number of of memory leaks (typically ~1500, probably it depends on complexity of menubar), most 
likely related to the app menubar. Below is small excerpt from leaks output:

Is this normal situation? Or there is something wrong with my code?

Is there a clean way to destroy the window with menubar without causing memory leaks? The description of 
gtkosxApplication seems to do not provide any hints...

Thank You in advance.
