Bug Description

Binary package hint: rhythmbox

Upgraded a fresh install of 9.10 to 10.04 Beta 1 (x86 desktop) to test support for a new 5th gen ipod nano. A few minutes after initializing the new ipod in rhythmbox (version 0.12.7git20100325-0ubuntu1), I right clicked on the IPOD entry (in the left panel of rhythmbox) and clicked on properties, and then rhythmbox crashed after a few moments (maybe a second or two on this older laptop). I started rhythmbox a few more times to see if the results were consistent, and every time I clicked on properties, rhythmbox would consistently crash in this manner. If you have any more questions, please let me know so I can get back to you ASAP (I know those of you working on 10.04 must be on a tight schedule, so I would like to help however I can).

Here are a few version numbers that might help:
ubuntu 10.04 Beta 1
rhythmbox 0.12.7git20100325-0ubuntu1
libgpod4 0.7.92-0ubuntu1
libplist1 1.1-1ubuntu1

Before I do anything else, I want to let you know what I've done.

I later tried plugging this iPod Nano 5g back into my 9.10 box, thinking that I would check to see if I could get the latest gtkpod compiled from source to work with it (in case the problem was upstream). However, when I plugged this iPod back into the 9.10 box after having "initialized" it on the 10.04 box, it no longer appeared.

Then, it what must have been a total lapse of sanity, I had a friend of mine plug it into his Windows box with iTunes, as I had read somewhere online that doing so "fixes" the filesystem layout in the iPod Nano 5g, at which point it can be used with the upstream libgpod. After plugging the iPod back into the 9.10 box, it still isn't recognized (I didn't bother to finish installing the upstream libgpod). However, now when I plug this iPod into my 10.04 box, the error does not occur. When dragging and dropping music files into the iPod before did nothing, I assumed that this was not valid behavior. However, this also works now.

This leads me to believe that this problem may have been an issue with the "initialization" process for the iPod Nano 5g.

I apologize for dropping the ball on this... is there anything I can do to salvage the situation? Resetting didn't seem to have any effect...

I have to same problem know with Rhythmbox 0.12.8
and I have seen this guy has the problem as well:
and this guy has the solution:
but it is still a bug in Rhythmbox I guess so i'm marking New.

My problem came about after a Rhythmbox crash that corrupted the iPod. Then I tried removing the FXX where X's are numbers from the Music directory because the ipod couldn't recognize the music anymore. That must mean that I am in the uninitalized state again.

I've had this problem too but after re-initializing IPod(Shuffle, 2nd gen) in windows iTunes, it is gone. Right now I'm on Rhythmbox 0.13.1 and it's not reproducible anymore.

Thank you for taking the time to report this bug and helping to make Ubuntu better. A new version of Rhythmbox is available on Maverick and we are wondering if this bug is still an issue for you with that version? Could you please test and comment back? Thanks in advance.
