The bug has been opened on https://bugs.launchpad.net/ubuntu/+source/rhythmbox/+bug/141584

"Binary package hint: rhythmbox

I have an iPod with Rockbox installed, and not the Apple DB.

Dies like so on the command line:

Does that patch help ?

Comment 2 Christophe Fergeau 2007-10-02 13:22:31 UTC

Oh, in fact I missed the part about the iPod not having an iTunesDB. The patch from revision 5277 might help.

Comment 3 Michael Moore 2007-10-02 14:42:48 UTC

Hi, I filed the original bug on Ubuntu's Launchpad. I'm just commenting here so I'll get future updates to this bug. 

Please let me know what I can do to help. I don't know the Rhythmbox codebase at all, but I can patch, recompile and test stuff pretty well. 

Thanks, 
Michael Moore

NB: bug #484892 has a much better backtrace. Did anyone check if the patch from rev 5277 help ?

Comment 7 Fabien Tassin 2007-11-29 15:19:49 UTC

I'm experiencing the same crash with rhythmbox from SVN r5454.
This is with an iPod nano. The crash disappears after the iPod is used at least once with iTunes. Any change in the content corrupts the database and let the iPod "appears" empty, and unrecognizable by iTunes, until it is reseted.
