Created attachment 133207 [details] KDE Global Menu activated
I think I found the cause of the problem. In KDE System Settings->Application Style->Window Decorations->Titlebar Buttons I enabled the Global Application Menu. With if I disable it (remove from the titlebar) okular opens new documents in new tabs as desired.
Okay, I definitely found the real problem. The application link command on my desktop to ocular was followed by " --unique %F", whatever that means, wherever that came from... removing it solved the problem. For debugging purposes I started okular via terminal "LANG=en okular", and this worked, while starting okular from my desktop icon link gave okulars wrong behavior... Its not a bug, just my stupidity :)
