Rhytmbox frezes when attempting to seek

[Munchkinguy]

Binary package hint: rhythmbox

When playing an audio file in Rhythmbox and then dragging the "play position indicator" toward the end of the file, Rhythmbox refuses to continue playing the file. Playback stops and any attempt to force it to resume will result in the entire application freezing.

The following message appears in the terminal:
(rhythmbox:7348): Rhythmbox-WARNING **: Failed to pause pipeline before seek

Thank you for taking the time to report this bug and helping to make Ubuntu better. Please try to obtain a backtrace following the instructions at http://wiki.ubuntu.com/DebuggingProgramCrash and upload the backtrace (as an attachment) to the bug report. This will greatly help us in tracking down your problem.

[Sebastien Bacher (seb128)]

also does using alsa rather than pulseaudio makes a difference?

[Munchkinguy (10068660)]

It doesn't crash. Just freezes indefinately. Also, I did this using alsa, not pulseaudio.

[Sebastien Bacher (seb128)]

can you get a stacktrace of the freeze using gdb?

[Munchkinguy (10068660)]

I tried:
(gdb) thread apply all bt
No registers.
(gdb) bt
No stack.

The thing is, the program doesn't crash. It just hangs until you use Force Quit to close it.

I had some success:

[Sebastien Bacher (seb128)]

the stacktrace lacks debug symbols, you need to install libgstreamer0.10-0-dbgsym libglib2.0-0-dbgsym and get a new one. could you also open the bug on bugzilla.gnome.org where people writting the code will read it?

[Matthew Woerly (nattgew)]

I have a similar problem with Intrepid. When I seek, it freezes the whole program right away. Is that what you're experiencing? You seem to indicate that it's only after you try to do something else that it freezes.
I was able to get a basic gdb trace, but I couldn't figure out how to get a backtrace since, like you said, it doesn't crash, it freezes.

[Munchkinguy (10068660)]

I installed the debug symbols. The trace is below. Please tell me if, in the future, you want me to attach the traces as separate text files.

[Matthew Woerly (nattgew)]

Ok, I did a backtrace for mine.

[Martin-Éric Racine (q-funk)]

I get this same bug, but at random and doing normal playback, when clicking on a new song while another is already playing back. Rhythmbox simply freezes while playing back some files, since Intrepid, with the same symptoms shown by others. The backtrace is similar too.

[Martin-Éric Racine (q-funk)]

To rephrase this better: I get random freezes while playing back some songs, and freezes after selecting a new song that interrupts playback of the current song.

We are closing this bug report because it lacks the information we need to investigate the problem, as described in the previous comments. Please reopen it if you can give us the missing information, and don't hesitate to submit bug reports in the future. To reopen the bug report you can click on the current status, under the Status column, and change the Status back to "New". Thanks again!

[Munchkinguy (10068660)]

We've responded to every request for further detail. If you would like something specific, please say so.

[Martin Mai (mrkanister-deactivatedaccount-deactivatedaccount)]

I am sorry, Munchkinguy, I made a misstake here. I had two bugs opened in my webbrowser and wanted to close the other one, but somehow I closed this one. I apologize.

[Munchkinguy (10068660)]

That's alright. Thanks for explaining.

[Pedro Villavicencio (pedro)]

more like a gstreamer issue. reassigning.

[Munchkinguy (10068660)]

In Ubuntu 10.04 Lucid, it is not possible to seek at all. If I click on a different position on the file, the play position indicator just jumps back to its original position.

[Matthew Woerly (nattgew)]

I just tried it with Lucid. Dragging the position indicator is working fine for me now (with an Ogg file). When I click on a position, it moves there and plays, but audio goes away. Once I click pause, the audio fades out and stops. I have to click play and then it plays fine.

[Munchkinguy (10068660)]

Yes, ogg vorbis and flac work fine. It is mp3 files that cause the problem.

[Matthew Woerly (nattgew)]

Hmm, I just tried an mp3 and it immediately started playing from whatever position I clicked on.

[Pedro Villavicencio (pedro)]

that's a different report, this was a duplicate of bug 270700. May you please open a new bug if you're facing something similar with Lucid? please use ubuntu-bug rhythmbox for that, thanks.
