* Make the 'delete my data' button not the default
* Make it red
* Give it a confirmation dialog
* Remove the 'cancel' button: what does it mean to cancel an error?
In this case, it tried again and almost certainly got the same error.
* Remove the top-right 'x' and don't cancel on esc for the same reason.
* Move 'send bug report' to a button rather than a 'click here' link
* Add a 'refresh' button which, even if it's no more likely to work,
will at least look like it's doing something (it's mostly so if you
don't have a bug report endpoint, there's still a button other
than the one that deletes all your data).
