When viewing a pdf file in krusader 2.5.0 (by hitting F3), the krviewer opens the file as a text file. When switching to the generic mode (Ctrl+Shift+G) to display the PDF, the message "No file selected or impossible to view the selected file" is shown; despite Okular working perfectly fine, the PDF Viewer used by the generic viewer to show PDFs. The same phenomenon with all other binary file types, such as mp3 say. It used to work fine under OpenSUSE 42.1.
