Just gone from 4.5.4 (which was working okay) to 4.5.5

When I hit dash, the featured items had disappeared.....went in and the catagories were still there, but all the items had gone....

Log dumped:

No external item found with id:cn=xxxx,cn=requestdefs,cn=appconfig,cn=userapplication,cn=xxx,ou=xxx,o=xxx
Even though the objects exist and the User App Admin account has rights to them....

I was able to action worktasks and the workflows continued, but the dash browse appears to have been severely ****ed up
