I do not see that profile.  I believe konqueror comes with just two
profiles: "File Management" and "Web Browsing".  Possibly your
"Midnight Commander" was added after the Trinity install, or you
have some old KDE 3.5 config files in play.

I avoid embedded spaces in "things" at all costs.  :-)  Try renaming the
profile to "Midnight_Commander" and test that.

What you're attempting _does_ work for me at the command line:
A split pane profile, with one or the other pane "active" when saving
the profile.  Then

konqueror --profile Midnight_Commander $HOME

... would open konqueror in split screen with the user's home directory
in the saved, active pane -- and the other panel totally blank -- ala
about:blank
