I had strange problem recently with a customer site.

A user could create pages but could not subsequently read them (published or not)

 

They were in an authoring group with the appropriate permissions.

 

This baffled me for a while but finally I tracked it down to permissions on the Master Page library - the user did not have any permissions on the Master Page Library.  So I gave the user "read" permissions to the Master Page Library and the user was able to read pages they had created.
