.. a quick follow on, you prob have loads of screen shots in your gallery too.
I ran a LogCat on my Galaxy Nexus Device (GSM), and can see before the dump begins it always happens right after the screen state gets set (*** Set_Screen_State 1)
I get usually all of my 'BugMailer' dumps when my phone is on the lock screen or being woken up!
