Yes… I will be looking at the permissions. That seems to be the most logical possibility. It is however confusing to a Newbie to the system (like me). It would be nice if it was a bit more informative rather than just saying it died though.
Granted, although at the same time you wouldn’t want to present the user with too much detail that might lead them to try and break through the permissions.
We’ve made permissions simpler in 1.8 so that there is a list of all the pages that corresponds exactly to what you see in the URL bar - this should make it simpler to work out which page is missing the necessary permission.
