Hi,
after updating to kde 4.14 Digikam won't start. I've tried to delete digikam4.db and thumbnails-digikam.db but Digikam still fails. What's wrong?

This it the console output:

Code: Select all

I'm using Archlinux

messages point towards the gstreamer phonon backend so I would suggest switching the phonon backend to VLC, then restarting KDE

you could also:
- reinstall all your gstreamer packages, there may be an issue there
- test as a new user

ps - sometimes helps to know what distro you are running

Hi google01103,
I'm using Archlinux. I've reinstalled some gstreamer package but the result is the same: a crash.

but....after installing phonon-vlc everything is ok.

Is vlc backend better than gstreamer backend or should I try to get gstreamer work again? Thanks

there are differences of which I can not specify other than VLC will not have an equalizer available in Amarok until v2.2, my experience is that VLC has been less problematic but obviously ymmv

What should I do if I wanted gstreamer to work again? Thanks.

does gstreamer work in other phonon based apps like Amarok?

are you using the current or legacy version of gstreamer?

I would suggest you re-install the gstreamer packages per the Arch wiki https://wiki.archlinux.org/index.php/GStreamer

there might be a packaging issue with either Digikam or gstreamer so maybe re-install both

if re-installation doesn't help try as a new user, you could have a corrupt rc file

After system update to kde sc 4.14 Digikam doesn't crash with gstreamer.

Thanks for you help, solved.
