I am trying to to open PDF files with Krusader but it does not do anything when I click on a pdf file (or hit Enter).
I set the system default application for pdf files so when I open the Ubuntu's default file browser and click on any pdf file it opens with Document Viewer. That is fine.
But when I do the same in Krusader nothing happens.
How can I tell to Krusader to use Document Viewer for open pdf files?
It seems that Krusader uses different applications to open files. For example Ubuntu's file browser uses Image Viewer to open jpg files but same image file is opened with Firefox by Krusader.
