rhythmbox crashed with SIGSEGV in free()

[iGadget]

Binary package hint: rhythmbox

When I tried dragging a selection of MP3 files on my local harddrive to a newly created playlist on my iPhone 3GS, Rhythmbox crashed.

I expected it to transfer the files to the iPhone and add them to the playlist.

Fully updated (as of april 10, 2010) Lucid AMD64 installation connected to an iPhone 3GS running firmware 3.1.3.

Thank you for taking the time to report this bug and helping to make Ubuntu better. Please try to obtain a valgrind log following the instructions at https://wiki.ubuntu.com/Valgrind and attach the file to the bug report. This will greatly help us in tracking down your problem.

[Pedro Villavicencio (pedro)]

this bug is very similar to bug https://bugzilla.gnome.org/show_bug.cgi?id=551194 on the upstream BTS , but we still need a valgrind log to send upstream and help the developers to fix it, thanks.

Pedro, thanks for your response. So can you confirm I should do the following (I've never worked with Valgrind before):
-Install Valgrind
-Install rhythmbox-dbg
-Run the following command in a console:
G_SLICE=always-malloc G_DEBUG=gc-friendly valgrind -v --tool=memcheck --leak-check=full --num-callers=40 --log-file=valgrind.log /usr/bin/rhythmbox %U
-Try to reproduce the bug
-Pack the Valgrind logfile and attach it here

Please let me know.

Decided to go ahead and try it before getting your answer (if my procedure is wrong I can always try again, right?). What surprises me is the following:
-I create a new playlist on the iPhone through Rhythmbox. A sync action is called, which seems to finish succesfully.
-I then rename the newly created playlist to 'test'. Again, a sync action is called, which also seems to finish succesfully.
-When I look on the iPhone, there's no playlist present, however (different bug?).
-I finally drag some test mp3's onto the playlist I just created... and nothing happens. I tried again a second and a third time - just nothing. Nothing gets displayed in the logs, rhythmbox does nothing, the iPhone doesn't sync... Just nothing happens.

It's kind of hard to reproduce a bug when the step leading to the bug fails entirely... :(

I attached a video of what happens. Feel free to remove it if it's not useful.

Now what?

[Pedro Villavicencio (pedro)]

Yes, that what you need to do.

[iGadget (igadget)]

Pedro, thanks for answering my question in #7. But I guess you missed #8. Can you help me that one?

[Pedro Villavicencio (pedro)]

Ok, so -When I look on the iPhone, there's no playlist present, however (different bug?). <- this is a different issue and it's known to not work fine on iPod devices, might be the same on the iPhone since the database is similar. And those issues you're describing are separates issues, here we're tracking the crash, feel free to open new bug reports for such problems though, thanks in advance.

the upstream bug has been closed as obsolete due to lack of information. since there have been no duplicates to this bug report. I am closing this bug now but feel free to report any other bugs you may find.
