OS:                Linux

amarok and dragonplayer are crashing when I try to play an ogg audio file with phonon gstreamer backend

phonon + phonon-gstreamer: todays git master
gstreamer-0.10.35
gst-plugins-ogg-0.10.35
gst-plugins-bad-0.10.22
gst-plugins-base-0.10.35
gst-plugins-good-0.10.30
gst-plugins-ugly-0.10.18

Reproducible: Always

Steps to Reproduce:
- set gstreamer phonon backend
- start an ogg file with dragonplayer/amarok

Actual Results:  
it crashes

Expected Results:  
it should play the file just fine like other media player

Application: Dragon Player (dragon), signal: Aborted

Comment 3 Alex Elsayed 2012-06-04 08:53:56 UTC 
First of all, thanks Myriam for pointing this bug out - not sure why I hadn't found it; I searched a bit before using drkonqi to submit the other one.

As far as my phonon-gstreamer version (as asked on the other bug), I'm on git HEAD c794f0ec3f8a6f18b878b1a0c59f54df9805f292, so definitely after the fix in comment #1, which 'git log' confirms.

fix crash due to wrong placed return

Comment 15 Myriam Schweingruber 2012-12-03 13:54:27 UTC 
Dear all who can reproduce this bug with the current phonon-backend-gtreamer 4.6.2, please have a look at the comments #11 and #12. We really need a test file and a debug log with all debugging parameters enabled, as described in http://techbase.kde.org/Development/Tutorials/Debugging/Phonon. Without that it is almost impossible to fix this bug.

Pardon, but git seems to indicate that GStreamer-1.x support has not yet been merged to phonon-gstreamer master (HEAD = 9dabadf41565a9bf35e5a7328dab8ea08b953506), much less backported into the 4.7 series (4.7 HEAD = 610de0ec5d6cbbf2a6a3ec937ed013ccf31eee66). I don't dispute the closing, but if anyone _does_ still experience this then reproducing with 4.7.2 and GStreamer-1.x might prove somewhat difficult.
