AppKit multi release bug

[Marko Mikulicic]

Hi,

I've set the "doubleReleaseCheck" in the main of Calculator.app.
A "doublerelease" exceptions is thrown in NSApplication finishLaunching the 
notification sent to NSWorkspace notification center:
(see wk-bt.txt attachment)

When I manually removed the first one from NSApplication.m the exception
is thrown later but also from DPSgrestore: (see second attachment)

I use the last cvs code.

Is mulireleaseCheck really telling the truth ?
I've tried with many AppKit examples and custom applications.
I suspect this to be the cause of my memory related bug,
because it is related with releasing views (but I
checked views release count manually and they seems ok).
