Description of problem:
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1.Navigate to services->catalogs
2.click on any catalog item in "All Catalog Items"
3.then navigate to settings->about page
Breadcrumb displayed.see attached screenshot.clicking on the breadcrumb link displays "The page you were looking for doesn't exist"
No breadcrumb should be displayed.
It looks like breadcrumbs links are being built incorrectly for catalog explorer. I think you need to add service_template to the list here https://github.com/ManageIQ/manageiq/blob/master/app/controllers/application_controller/ci_processing.rb#L1061 let me know if you need help with recreating this or need further help with this.
I can't reproduce it on master nor on 5.5.4 nor 126.96.36.199. It looks like there is no longer a breadcrumb.
