Thread: "knotify closed unexpectedly" when using dolphin or konqueror Delete item

    Default "knotify closed unexpectedly" when using dolphin or konqueror Delete item

    I have delete enabled in right button menu in konqueror and dolphin. Since some days ago (and I don't remember when nor if I did something) when i try to delete one or more items i get a error message "knotify closed unexpectedl" at the same time that the popup appears asking for confirmation to delete the item.
    I can close the knotify error message and I can continue deleting the item "as if nothing had happened", but i would like to wnok why it happens.
    Here is the debug log of knotify

    Code:
     Application: KNotify (knotify4), signal: Segmentation fault

    I have reinstalled the package wich contains knotify (I don't remember now which is, but I searched it with yast and forced a reinstallation), but it did not solve the problem.
    I see the problem seem to star in /lib64/libc.so.6 so may be a libc6 problem?

    regards

    Uninstall phonon-backend-vlc, this does not work at all with VLC 2.2, as it is built against VLC 2.1 (and it has other severe problems as well).

    I see the problem seem to star in /lib64/libc.so.6 so may be a libc6 problem?
    No. Actually it is a clash between Qt4 and Qt5 (loaded by VLC), but even without that crash it wouldn't work.
    Your phonon-backend-vlc uses the libvlccore7 from VLC 2.1, but you only have the plugins and codecs for 2.2 installed.

    If you insist on using the VLC backend, you'd need to downgrade VLC to 2.1, but the version included in openSUSE 13.2 doesn't come with restricted codecs.

    OK solved. It may be there as a result of an upgrade of the OS from a previous version.

    thanks.

    Well, phonon-backend-vlc is (still) part of the distribution. But it only works with the VLC version that's also included in the distribution, not with later ones you might have installed from Packman or the VLC repo.
    There's not much that can be done about that, maybe Packman should provide phonon-backend-vlc built against their VLC. They did until a few months ago (unnecessarily, because 2.1.x was the latest version back then so the openSUSE phonon-backend-vlc worked with VLC from Packman anyway), but removed it for some reason.

    On Tumbleweed this is no problem though, as it contains the latest VLC version anyway.

    But as mentioned, phonon-backend-vlc has other problems as well (when PulseAudio is in use), e.g. it raises the volume to 100% whenever a notification sound is played. And it lacks features compared to the default gstreamer backend.

    All in all you're probably better off with the gstreamer backend, I suppose.
