How do I create a simple breadcrumb with pathauto?
I guess easy_breadcrumb module would be good to use for this scenario. 


  The Easy Breadcrumb module provides a plug-and-play block to be embedded in your pages, typically at some place near the page's header. Easy Breadcrumb uses the current URL (path alias) and the current page's title to automatically extract the breadcrumb's segments and its respective links.


Example: URL like gallery/videos/once-a-time-in-cartagena, Easy Breadcrumb will automatically produces the breadcrumb as


  Home >> Gallery >> Videos >> Once a time in Cartagena 


or


  Home >> Videos >> Once a Time in Cartagena 


Again, the breadcrumb presentation will vary depending on your module's settings.
