[Qt-interest] Qt 4.7.1 & Mac :: Cocoa widgets seem to be leaking ram (bug - reported)

[John Porter]

http://bugreports.qt.nokia.com/browse/QTBUG-16488

How to recreate:

Open the sample Qt file located at:
Qt/Demos/MacMainWindow/
Build (from x-code)
Run app.
Quit app.
Look at the Debugger console and you should see error code such as this:

I have narrowed this down to the search bar (which is a Cocoa search field).
If you comment this code out, the errors go away.
Even though this affects a sample project, I am unable to use the search field 
code in my own apps due to this Cocoa leak.
Bottom line, the current implementation of the cocoa search bar in Qt/mac (cocoa 
4.7.1) leaks memory.
