Photoshop crash on mac in 'slct' event callback

Question

Hi,
I am getting consistent  Photoshop crash on mac (12.0.4) when handling 'slct' event callback in my extension
The crash itself produce the same repor (see bellow) t as described  here: http://forums.adobe.com/message/3473893#3473893
I narrowed it down to the case when you have 2 or more documents in "consolidate all to tabs" mode and you try to  pull out one of them.
If you have a callback registered like this for 'slct' ExternalInterface.addCallback("PhotoshopCallback" + CSXSInterface.instance.getExtensionId(), eventCallback) and you try to access Photoshop.app.activeDocument Photoshop crashes with the bellow report
It's hapening onlyon mac.
Do you have any advice how to workaround it or even better a fix?
Regards

Sure, I know about PSEvenScrubber. This on is different beast though. When activeDocument is null it's just it and you get an exception in the script if you try to use it, but in this case code like this:
var ho:HostObject=app.activeDocument.hostObjectDelegate or
var d:int=Photoshop.app.documents.length;
cause the crash of the whole Photoshop
Keep in mind that if i just switch between the documents without pulling them out of the dock everything works fine.
But it can be releated though as it seems that something is not initialized properly, but in this case on deeper level than actionScript
