The following is the top bit of an apple crash report.
Latest mac binary PyQt4, plus Qt 4.8.4. Only happens in the
version bundled by pyinstaller - never running from source
in the IDE.
The crash follows cmd-q quit after a normal work session.
The main window closeEvent does a number of settings writes
in a beginWriteArray loop.
However, I notice now, that after settings, it never calls
event.accept() on the closeEvent object -- could that matter?
