--- Comment #4 from Éric Brunet <eric.bru...@lps.ens.fr> --- So, on my uptodate fedora 23, I downloaded the file http://mirror.rit.edu/archlinux/testing/os/x86_64/kamera-15.12.0-1-x86_64.pkg.tar.xz from the archlinux distribution and manually put the files kcm_kamera.so and kio_kamera.so into /usr/lib64/qt5/plugins, and the files camera.protocol and kamera.desktop into /usr/share/kservices5, and the file solid_camera.desktop into /usr/share/solid/actions. In logged out of my kde session, logged in again and tried my camera. 1) on plugging my camera, a notification happens, and I can click on the "devices" icon to look at my possible actions. Good. 2) it proposes to open my camera in the file manager. Good. 3) clicking on the action, dolphin opens. I can browse my camera, display previews and copy files from my camera to the computer file system. Good. 4) HOWEVER, if I click on a photo to open it, it fires up okular which fails to open the photo: okular's window appears empty, and after about fifteen seconds an error window appears with the message: Could not open camera:/Fuji%2520FinePix%2520X10@usb:001,006/store_10000001/DCIM/111_FUJI/DSCF1377.JPG. Reason: Unknown error Impossible de communiquer avec le périphérique USB (the last sentence being "impossible to communicate with the USB device") After closing the error message in okular, I can go to the File->Open Recent dialog. The URL of the photo I tried to open is there and if I attempt to open it from here, it works AFTER A COUPLE OF TRIES. (On the first tries it usually fails with the same error message, but without the fifteen second wait. After a couple of atttempts it works, and once it worked, all the subsequent tries work also) >From okular, I can also go to the File->Open dialog, and type camera:/ and access my files without any problem. And now, for the very weird stuff: from dolphin, if I right-click a file to open the contextual menu, select "open with" and then "okular", it works most of the time: the file opens. Sometimes, it opens after a very small wait (1 second), sometimes one has to wait about 10 seconds, sometimes it fails after 15 seconds. I cannot make sense of this! So, okular is not a kf5 application -- You are receiving this mail because: You are watching all bug changes.
