Capability report:

• When an override permision is set somewhere (and it should display 'a tree' of contexts), it breaks with:
  This is an unknown context () in print_context_name!

Override permissions tab:

• Not checked if you touched this page, but overridden permissions are not being displayed as set (though the summary of overridden permissions per tab does show that 1 permission has been overridden) - need to check this in HEAD too
