Comment 1 Massimo Cora' 2010-05-14 12:22:39 UTC

I'm on an ubuntu 10.04 fresh installed.

Comment 2 Bastien Nocera 2010-05-14 12:33:37 UTC

Please install the debug packages for rhythmbox and libgpod and reproduce the problem, the stack trace is missing details.

Comment 3 Massimo Cora' 2010-05-14 13:13:12 UTC

I cannot find libgpod, but I installed the ones for rhythmbox.

Here it is the new stacktrace

Comment 4 Massimo Cora' 2010-05-14 13:20:51 UTC

Please not that in the current version of ubuntu's libgpod

$ dpkg -l | grep libgpo
ii  libgpod-common                       0.7.93-0ubuntu1                                 common files for libgpod
ii  libgpod4                             0.7.93-0ubuntu1                                 library to read and write songs and artwork 


my ipod shuffle isn't yet supported, and that's probably why there's a NULL pointer passed to rb_ipod_db_get_mount_path (ipod_db=0x0).

The support for ipod shuffle is on git

*** Bug 628122 has been marked as a duplicate of this bug. ***

Comment 7 Akhil Laddha 2010-09-05 13:51:42 UTC

can be a dupe of bug 614952

Comment 8 Christophe Fergeau 2010-09-05 17:02:43 UTC

Yep, that's likely even though I'd make bug #614952 a duplicate of this one since it has a more detailed backtrace.

Comment 9 Pedro Villavicencio 2010-09-30 16:31:36 UTC

we have a similar crash on bug https://bugs.edge.launchpad.net/rhythmbox/+bug/651261

Comment 11 Jonathan Matthew 2010-10-13 12:07:17 UTC

Commit 703fe04 should have fixed this.  I don't have an ipod to test with, let alone a broken one, so I can't be sure..
