hi

whenever i play something, i get this error 2/3 times a second:
(process:13012): GLib-GObject-WARNING **: invalid cast from `GstDecodeBin\' to `GstVorbisDec\'
i saw another thread with the same errormessage, and the solution mentioned was to upgrade gstreamer, so i updated through yum to 0.8.7 but the message is still there.
also, when amarok finishes playing a track, it crashes, unless it reaches the end of the playlist.
my amarok is 1.2.4 build from source

Your GStreamer is too old. Needs to be upgraded.

Oh, and not only GStreamer, but also Gst-plugins.

thanks for the quick answer
i\'ll try to build them from source then

gstreamer is now 0.8.10 and plugins 0.8.9 and everything\'s working perfect
thank you
