Dolphin mostly wants to play a sound file once it is selected, but then complains about missing plugins. For a midi file it wants to install gstreamer-0_10-plugins-bad, but then complains: cannot install both gstreamer-0_10-plugins-bad-0.10.23-13.1.4.x86_64 and gstreamer-0_10-plugins-bad-0.10.23-172.22.x86_64 0.10.23-172.22.x86_64 is already installed, so no wonder why it fails. Question is why it wants to install the old version. Not sure if this is a problem in dolphin 14.12.3, or if this is an unknown customizing setting.... Reproducible: Always Steps to Reproduce: 1. see above 2. 3.
This is a packaging issue (sounds like missing codecs in openSUSE), closing as such.
