Bug Description

Binary package hint: rhythmbox

Linux prime 2.6.24-19-generic #1 SMP Wed Aug 20 17:53:40 UTC 2008 x86_64 GNU/Linux
Distributor ID: Ubuntu
Description: Ubuntu 8.04.1
Release: 8.04
Codename: hardy

Architecture: amd64
Version: 0.11.5-0ubuntu8

Rhythmbox crashes while I drag the bar around trying to change position in the song.
Expected: The song skips to a position represented by the progress bar
What Happens instead: First the song stops playing, then the bar becomes unresponsive, then the entire program becomes unresponsive and must be killed.

Attached a backtrace. Hope this helps.

Valgrind output.

did you get the issue while getting this log? there is no crash listed there

Crap.

Valgrind slowed down the program a lot, as the wiki said it would. After rhythmbox opened I started to play the song and such and it seemed like it had slowed to a stop and crashed, but it may have just been valgrind slowing it down. Sorry, I'll run it again tonight and see if I can get a definitive crash.

valgrind workaround crashes sometimes but you can look in the log for invalid read or write errors

OK, here is a new Valgrind, but it doesn't look that much more helpful than the other one. I don't know what I'm doing with Valgrind, though, so maybe there is something in it. I did the same thing that I normally do to reproduce the bug, and the program seemed to hang. I gave it several minutes to make sure it wasn't just Valgrind being slow. Hopefully it shows up in this log.

If I'm not using Valgrind and i just run the program for the console, I can see it actually report a Segmentation Fault sometimes.

Sorry about the double post.

Additionally, this might be helpful. It is just some of the last lines of output from rhythmbox -d
I also tried the file in VLC and VLC handled it with no problems.

do you use the crossfading option? does not using it workaround the issue?

Yes, actually. I hadn't thought to check that before.
The issue goes away when I turn off cross-fading.
