I thought this had been fixed. :-/
I was told that it is not a simple fix because of some dependencies with the KDE framework (and perhaps Qt) but that it was done. Well, apparently there was some regression or it is in one of the nightly builds. I may not remember correctly which release this was going in.
At any rate, even though it still opens the old page there is a link there to the new official Kdenlive documentation (or manual, if you prefer). So, yeah it is one more click but what is one more click, huh?
