Hi all, I get the error "The process for the file protocol died unexpectedly." if I press, for example, File/Open" or "File/Save in Okular (version 0.26.1). All apps with that error message are using KDE development platform 4.14.26 (Information of Help/About <programname>, the dependencies and "lsof -p PID"). I'm wondering about that, because the concerned programs are KDE 5 programs and as far as I know, KDE 4 libraries and programs are discontinued. I got that error message at the first time after a upgrade (I'm using Debian testing). I tried to solve it by moving /var/tmp/kdecache-<username> and some KDE files files in ~/.cache to backup folders, but it didn't helped. How to solve that problem? Thank you in advance, Kai
