Bug 395226

When clearing the address bar of dolphin then selecting a kio-slave in the appearing dropdown box it gets entered in the address bar with two slashes at the end (example: "tags://", "timeline://", "settings://"). Pressing return on that one displayes the "root" of the kio-slave just fine...but if trying to navigate into the virtual "subfolders" of a kio-slave results in an "Invalid Protocol" error. If one of the trailing slashes is removed manually from the address bar folder navigation is possible again.

Version: 18.04.2 (Sorry, was missing in the dropdown above)

Steps to reproduce:

- start dolphin
- Click the address bar and delete everything
- Select the more->"Timeline" kioslave (but works with everyone, this one just is guaranteed the have at least a "today" virtual subfolder)
- "timeline://" is entered in the address bar
- press <return> to load
- "today" and "Calendar" folders are displayed
- click the "today" folder to open it
- "Invalid Protocoll" (German setting here..."Ungültiges Protokol", guess the English message at the moment)

A bit more details
- Click the address bar again and only remove the last "/" from "timeline://" then press <return> again
- click "today" folder again...works now


Expected behaviour:
I am not sure what the exact expected behaviour is. In general...that I can open folder directly after selecting a kio-slave from the dropdown. But not sure if the two "slashes" are the problem...I don't really see why any leading additional slash should change anything.."////home/" in the adddressbar still opens /home. So either allowing dolphin an arbitrator amount of slashes between kio-slave protocol and first subfolder...or at least having the dropdown insert the kio-slave with only one slash so that is works right away.
