Rhythmbox crashes after downloading a podcast

[Gannin]

Every second or third time I download a podcast, after the podcast has finished downloading and the status has changed to "Downloaded", Rhythmbox will crash. Aport doesn't come up, no other messages. Rhythmbox just crashes as though it was closed. This just started in Intrepid.

Thank you for taking the time to report this bug and helping to make Ubuntu better. However, your crash report is either missing or challenging to deal with as a '.crash' file. Please follow these instructions to have apport report a new bug about your crash that can be dealt with by the automatic retracer.

 If you are running the Ubuntu Stable Release you might need to enable apport in /etc/default/apport and restart.

 If you are using Ubuntu with the Gnome desktop environment - launch nautilus and navigate to your /var/crash directory and double click on the crash report you wish to submit.

 If you are using Kubuntu or Xubuntu you can file the crash using /usr/share/apport/apport-qt --crash-file=/var/crash/_my_crash_report.crash in a terminal - where _my_crash_report.crash is the crash you would like to report.
 I'm closing this bug report since the process outlined above will automatically open a new bug report which can then dealt with more efficiently. Thanks in advance for your cooperation and understanding.

There is no crash report. As I said before, Rhythmbox closes just as if you were the one to close it. Apport doesn't run, no crash report is generated. It just closes on its own. So I suppose that means this bug will now be ignored and simply won't get fixed. Wonderful.

[Sebastien Bacher (seb128)]

there is no reason rhythmbox should just close, can you get a gdb stacktrace?

[Gannin (spacesword)]

I'm unfamiliar with how to use gdb, so I'll need a bit of instruction on how to do that.

[Sebastien Bacher (seb128)]

http://wiki.ubuntu.com/DebuggingProgramCrash explains how to use gdb to get a stacktrace

you can also use these instructions to have apport report a new bug about your crash that can be dealt with by the automatic retracer.

I am also having the same problem with Intrepid.

After trying to enable apport using your instructions above, it says that I do not have permission to save the file. Is there a way of overriding this? (sorry, I am new to Ubuntu!). There are no files in the crash directory at the moment.

After downloading a podcast, Rhythmbox stops responding. If it is minimised to the taskbar, it does not display properly when maximised and has to be forced to quit.

[Sebastien Bacher (seb128)]

why did you reopen the bug, it doesn't have the required informations to be worked

[Patrick Den (pat31)]

I am also having the same problem (with Intrepid).
With the Intrepid updates of the last weeks, rhythmbox improved a little, but the problem is yet not solved.
While downloading a podcast, my CPU is almost at 100%. This causes sometimes the user-interface of rhythmbox to crash, and sometimes rhythmbox completely crashes. If other processes are busy it is more likely that rhythmbox will crash.
If multiple podcasts are downloaded, rhythmbox always crashes after the first one has been downloaded.

More than one bug on launchpad mention this problem. They should be tied together?

[David Parker (dparker)]

I am having the same problem, also on Intrepid. As soon as a podcast finishes downloading rhythmbox segfaults with no apport report. It is reproducible every time and seems to always die after downloading the third podcast in the download queue:

Here is a backtrace from gdb.

This is consistent, Rhythmbox will crash every time more than one or two podcast episodes are downloaded. The below trace is on Intrepid x86_64, updated to the latest available versions for all packages as of 2008-11-29T06:00:00 UTC.

I am experiencing the same problem. Rhythmbox crashes if I download two or three podcast. I will launch rhuyhmbox double click on a couple of podcast to download them and rhythmbox crashes. I am attaching the results of:

 rhythmbox --debug &> rhythmbox-debug.txt

[Scott Minster (sminster)]

I've seen the same problem with Rhythmbox since upgrading to Intrepid. Searching the bug reports, I found this one: https://bugs.launchpad.net/ubuntu/+source/rhythmbox/+bug/276603, which references this Gnome bug: http://bugzilla.gnome.org/show_bug.cgi?id=554556. The description isn't exactly the same, but the stack trace is very similar. The report indicates that the bug was fixed upstream. The Ubuntu bug has instructions for building your own patched version. Maybe Ubuntu could apply this patch into an update for the Intrepid version?

[James Lewis (james-fsck)]

I have the same problem, in 8.10 with 0.11.6 (64 bit), I can download podcasts for 2 or 3 minutes, then segfault, I have attached an strace output incase this will help..... it seems to be related to an issue with gvfsd-http which is found to be using almost 2Gb of memory after a few tries.... That seems to have been reported separately as bug 225615 with people reporting that it occurs when downloading podcasts...

This looks like it might be useful:-

[Sebastien Bacher (seb128)]

the crash is similar to bug #276603

[markofealing (mark-ferns16)]

Confirmed - solution supplied in bug #276603 fixes this problem.
