So now you get:
qemu-system-arm: Insufficient permission to perform this operation
Aborted

This still isn't really very diagnostic: I had to run the whole
thing under a debugger and look at the backtrace anyway before
I realised I'd hit the same problem again. Isn't there some way
to supply a more specific message than this? (some string that
actuall mentions at least one of "object", "property" and
"after initialization", for example :-))
