I am not aware of any such problems -- the system clearly uses startActivity() a -lot- for all of its normal UI, and I have never seen spurious security exceptions.
If you want to debug it, you need to debug the system code -- this is running in the system process, and the class is ActivityManagerService. You'll want to attach the debugger there, and put a breakpoint in the activity manager's public startActivity call. There should also be a log message printed when the security exception is generated, telling you pretty completely why it happened (though the output can be a little hard to decipher). It would be useful if you posted this information.
