[Sebastien Bacher (seb128)]

Thank you for taking the time to report this bug and helping to make Ubuntu better. Please answer these questions:
* Is this reproducible?
* If so, what specific steps should we take to recreate this bug?

This will help us to find and resolve the problem.

[Sebastien Bacher (seb128)]

Do you filter the view and then try to interact with the content while it was updating?

[Simon P. (simpre)]

No, I do not filter the view of my music library. And yes, on my system I can reproduce the bug:

1) Open Rythmbox
2) Add a song from the music library to the queue
3) Go to the queue and click on the song that was just added to play it.

Normally Rhythmbox will crash now. If not, repeat steps 2 and 3.

[Simon P. (simpre)]

The reason for my crashes of Rhythmbox seems to be the alternative appearance extension. With the extension disabled in the program settings I cannot reproduce those crashes.

[fossfreedom (fossfreedom)]

Please can you describe the exact steps how you add tracks to the queue to make this crash please?

Also, please run

rhythmbox -D alttoolbar

Then perform the action to make the crash happen. Please attach the output you see in the terminal.

Thanks.

[Simon P. (simpre)]

I add tracks to the queue by right-clicking them and then clicking the "add to queue" option.
The output of the "rhythmbox -D alttoolbar" command is:

[fossfreedom (fossfreedom)]

I cannot make this crash as reported. If you can please can you make a short screenrecorder so that I can see what you are doing and to view your rhythmbox setup. Thanks.

[fossfreedom (fossfreedom)]

please can you go into plugin preferences - alternative toolbar and untick "enhanced sidebar". Restart Rhythmbox. Can you make rhythmbox crash after that?

[Simon P. (simpre)]

Yes, I can still make Rhythmbox crash with a disabled enhanced sidebar.
Noticed another little bug by the way while disabling it: When the alternative toolbar is enabled, I cannot go into plugin preferences.

Screencast of my crashes is attached.

[rithik g (gkrithi)]

Happens only with german language ( LANG=de_DE.UTF-8 )
