@meven There is a weird bug if I name the protocol as "7z" or "7zip": 1. If I double click on the 7z file, Dolphin gives the "invalid protocol" error. 2. If I try to manually enter the URL in Dolphin, i.e. `7z:/tmp/bar.7z` or `7zip:/tmp/bar.7z`, it does not work too - it is somehow being treated as a host (hostname) instead of a protocol. I suspect that a KIO protocol should not have a name that starts with a number, otherwise there will be bugs.
