When debugging, I also often break there (due to an NSException being
raised). Like you, I've never figured out how this is useful.
Normally exceptions are printed to the console, with some kind of
information about them?
In Xcode's debugger, you can type this command:
po $r3
And it will tell you what the exception is about. Ironically, I've
found that things that are outside my scope (AppKit code), usually
causes these exceptions.
Hopefully someone else has a better idea on how to do something
constructive with these exceptions, this is all I've figured out
about them so far.

I have an application I have developed which crashes when customers
have voice over turned on (and I think it also crashes with some
other assistive settings turned on too).
The stack trace goes
NSAccessibilityAttributeValue
CopyAppKitUIElementAttributeValueNoCatch
CopyAttributeValue
_AXXMIGCopyAttributeValue
_XCopyAttributeValue
mshMIGPerform
__CFRunLoopDoSource1
__CFRunLoopRun
CFRunLoopRunSpecific

I can't see any way of getting at any useful data about the issue,
so would really appreciate any help with debugging this.
My guess is that something I am doing is screwing up some view
hierarchy or something.
Sorry if this question has been asked before, but Apple's mailing
list search seems to be broken.
Thanks
