Description telemetron 2013-07-03 16:06:37 UTC 
Application: amarok (2.7.1)
KDE Platform Version: 4.10.4
Qt Version: 4.8.4
Operating System: Linux 3.8.0-25-generic i686
Distribution: Ubuntu 13.04

-- Information about the crash:
- What I was doing when the application crashed:
Crash occurs on close of any additional window. 
Updating song rating from control on main screen does not crash, but opening the song details to edit the rating crashes when the window closes. 
Opening the About Amarok dialog and then closing it causes crash, so does opening and then closing configure amarok dialog and several other examples.
Running amarok --debug --nofork terminates with this message on crash:
The program 'amarok' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadWindow (invalid Window parameter)'.
  (Details: serial 4710 error_code 3 request_code 20 minor_code 0)
  (Note to programmers: normally, X errors are reported asynchronously;
   that is, you will receive the error a while after causing it.
   To debug your program, run it with the --sync command line
   option to change this behavior. You can then get a meaningful
   backtrace from your debugger if you break on the gdk_x_error() function.)

The crash can be reproduced every time.

-- Backtrace:
Application: Amarok (amarok), signal: Segmentation fault

Quick google search suggests this may be related to KDE and recent update to Raring... I don't use many KDE applications on a regular basis and can't confirm this.
Comment 2 Myriam Schweingruber 2013-07-03 18:06:01 UTC 
The problem is with the phonon-backend-gstreamer,  not with amarok

*** This bug has been marked as a duplicate of bug 293951 ***
Comment 3 telemetron 2013-07-03 20:59:28 UTC 
Switching to the VLC backend does not resolve the issue.
Previously was told that the gstreamer backend was causing a different issue, switching to the VLC backend didn't resolve those either (disabling the Wikipedia plugin finally made it stop), but the VLC backend had issues too, and I was told that that set of issues was resolved in one of the latest updates.
Not clear why the phonon backend would cause Amarok to close unexpectedly on a dialog close and throw an X error, regardless of current audio state (the crash occurs whether audio is playing or not), and why backtrace and symptom description bear no resemblance between this and the 'duplicate' bug.
Hoping that this draws attention to what must be a serious bug if it has continued to be unresolved for more than a year and apparently keeps some people from even being able to start their media players, also hoping that whatever gets done to resolve that other guy's issue by some freak miracle also resolves mine.

Please see this line in the crash report: 
#17 Phonon::Gstreamer::Pipeline::cb_state (bus=bus@entry=0x9e7dcd0, gstMessage=0xb3d3e88, data=data@entry=0xa254a50) at ../../gstreamer/pipeline.cpp:356

That's where the crash happens, and it is the same in the master bug. Your other comments are unrelated as you are clearly mixing different issues here.
