Description Martin Szulecki 2006-03-11 02:03:45 UTC

banshee segfaults on startup when my iPod (FAT32) 3G Firewire is mounted.

Command Line:
---
<:~/> banshee

Description:

I THINK this does not affect regular iPod users as mine contains iPodlinux which resides on an extra ext3 partition on the iPod disk. I assume some routines (or libraries) in banshee do not compensate for this and might get "disturbed" by the two "iPod's". (However unmounting the ext3 partition did not help. Only unounting the main iPod partition makes banshee startup. I hope banshee does not generally fail with an iPod mounted.)

- banshee-plugins-default (0.10.7-3 / _0.10.7-3)

Attempts to fix it WITHOUT success (same segfault):

- Reinstalled all packages
- umount /media/disk/ (unmount that supposingly problematic partition)

Attempts to fix with success:

- Unmount iPod device
- Use Rhythmbox instead

Comment 3 Christian Boltz 2006-03-11 12:10:41 UTC

IMHO, a segfault can't be minor...

BTW, your description sounds like the ext3 partition doesn't have to do much with the problem - but I'm not sure about that.
What happens if you umount the vfat partition and keep the ext3 mounted?

Comment 5 Martin Szulecki 2006-03-11 13:13:35 UTC

Unmounting the regular IPOD partition prevents the crash to happen.
So assuming more or less the ext3 partition has not much to do with the problem.

Comment #4 above's bug-duplicate contains more information including backtrace which points to a problem in libipoddevice.

...
#17 0xb3106538 in ipod_device_new () from /usr/lib/libipoddevice.so.0
..

BTW: Sorry for duplicates however yesterday the novell site took a long time to react when commiting and I was prepsented with an error site (site timeout) where I was not aware that the bugreport had infact already been posted...

Comment 9 Martin Szulecki 2006-04-11 10:57:02 UTC

Bug applies to all 2G and lower generation iPod's with which banshee won't work.

Issue was in libipoddevice 0.4.1.

Bug fixed in CVS Head and upcoming 0.4.3 (http://bugzilla.gnome.org/show_bug.cgi?id=338006).

Comment 10 Martin Szulecki 2006-04-21 14:28:34 UTC

I recommend upgrading the package to the latest version from here:

http://banshee-project.org/Subprojects/Libipoddevice

Just bumbing this, as it is very easy to fix and I got fears it won't make it into the release of 10.1. (Will draw banshee unusable for all 1G and 2G iPod owners)

Comment 11 JP Rosevear 2006-04-24 16:12:21 UTC

We work closely with Aaron on banshee issues.  I've submitted the fix for RC3.

Also bumping up the severity, this did actually turn out to be pretty critical.
