Another dolphin question:
I like to use dolphin in a two panel view, much like midnight commander.
However, how do I copy the location/path of one panel to the other, so that both are the same?
In mc I have a button/key combination for that.

If you click on the right most side of both bread crumbs, the paths should switch to fully editable paths. You should then be able to copy it over to the other side. Unfortunately you can't automate this as far as I know.

Newly split panels will always start in the same location.

Yes, but that is a fairly manual and cumbersome copy & paste process. This is not particularly user friendly.
There should be a couple of (toolbar?) arrows ">" "<" to copy paths from one panel to the other.
A single "=" would also work if you adopt the convention that the active panel copies to the non-active.
However, this would be less intuitive than the first option.

This seems to be related (although a bit confusing, also read the comments): https://bugs.kde.org/show_bug.cgi?id=146733

The fastest way now, as far as I know, is to close and reopen the split view. Yeah, not very elegant.

Good to know it is not me who is overlooking something obvious.
Sometimes one would hope some more attention is given to these annoying usability issues in stead of all that KDE4 eye-candy.
This makes me wonder: Didn´t Kommander in KDE3 had such a button?
