Okular can't open pdf files from SFTP

Hello,

I think there’s a bug in Okular (I will report it later). I can’t seem to open pdf files from SFTP filesystem.

But why is Dolphin not mounting SFTP in local filesystem instead of using this weird thing (sftp://) ? When mounting the SFTP with sshfs, it works really well and even with apps that doesn’t support remote FS.
sftp://maledict@192.168.1.30/home/maledict/Drive/Cours/Licence/Info3/SR1/Cours/

Okular error :
Impossible d’ouvrir « sftp://maledict@192.168.1.30/home/maledict/Drive/Cours/Licence/Info3/SR1/Cours/01-Intro-SE-Unix-C.pdf ». Raison : Échec lors de la communication avec le gestionnaire de mots de passe
