Disabling visualization while playing audio hangs Totem

[Louis Simard]

Binary package hint: totem

While playing an audio file in Totem, if a user goes to Edit/Preferences, then the Display tab to disable visualizations, Totem hangs. It continues playing the current file, but Repeat mode cannot be honored thereafter and the rest of the UI freezes. CPU usage for Totem is still 0%, so it's probably not an infinite loop anywhere.

Steps to reproduce:

1. Tick Edit/Repeat mode.
2. In Edit/Preferences/Display, make sure a visualization is selected, such as GOOM, and enabled.
3. Open any audio file.
4. While the file is playing, go to Edit/Preferences/Display again to disable the visualization.

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.

Attached a stack trace with threads and debug symbols.

I am playing Aesop's Fables, from Ubuntu's example-content, which explains the ogg thread. Threads 1 and 9 seem to be caught in a deadlock, but the devs will know better.

Also tentatively marking gstreamer as affected, because the visualizations are in gstreamer0.10-good.

[Louis Simard (louis-simard-deactivatedaccount)]

Erm. I edited the affected package instead of adding it, which reset the importance and status. It should still be Low, Incomplete.

Whoops!

The bug should probably be sent upstream to bugzilla.gnome.org by somebody able to trigger the issue

[Sebastien Bacher (seb128)]

the issue is a gstreamer one

[Louis Simard (louis-simard-deactivatedaccount)]

That's what I thought, but I wasn't really sure if visualizations were in Totem or in GStreamer at first. Will file a report in GNOMEzilla and attach a remote bug check if applicable.

deassigning Ubuntu Desktop Bugs so it's possible to attach a remote bug check

[Louis Simard (louis-simard-deactivatedaccount)]

and it seems I can't attach a remote bug check after all; please see https://bugzilla.gnome.org/show_bug.cgi?id=583255

This is not an issue anymore in Karmic alpha 6.
