[Flavio Tordini]

Binary package hint: phonon-backend-gstreamer

This is the error:
GStreamer-CRITICAL **: gst_element_make_from_uri: assertion `gst_uri_is_valid (uri)' failed

To reproduced just use the Qt demo mediaplayer in /usr/lib/qt4/demos/mediaplayer

What file are you trying to play?

Same problem here using karmic on i386.

You can reproduce the error using the demo musicplayer in /usr/lib/qt4/examples/phonon/musicplayer
GStreamer-CRITICAL **: gst_element_make_from_uri: assertion `gst_uri_is_valid (uri)' failed

gstreamer and plugins are installed and working without any problems with gst-launch-0.10
gst-launch-0.10 playbin uri=file:/path/to/file.mp3 gives no errors

@Jonathan
It does not work with any kind of files.
Btw why this is marked as incomplete? What info is missing in the report?

[Jonathan Thomas (echidnaman)]

This should be fixed in Kubuntu 10.04. Make sure you have gstreamer0.10-plugins-good installed, though.

[SurJector (loic-grenie)]

Will it be fixed *in Karmic* ?

[Jonathan Thomas (echidnaman)]

You can upgrade to KDE 4.4 in Karmic, if you wish: http://www.kubuntu.org/news/kde-sc-4.4.2
