Segmentation error when dragging file from library to smartphone

[Daniel Ejsing-Duun]

I connect the iPhone, open Rhythmbox (in any order),search the library for the files (mp3 and ogg files at least affected) and drag one of them to the iPhone in the left sidebar. Rhythmbox crashes immediately.

Here is the output (only last two lines are printed at the actual crash):
$ rhythmbox

As an added note: This worked in Ubuntu 11.10 before upgrading to 12.04.
Output from apport-bug has been attached.

Status changed to 'Confirmed' because the bug affects multiple users.

I have exactly the same problem with rhythmbox 2.96 on Ubuntu 12.04. The player is an android device.

Thank you for taking the time to report this bug and helping to make Ubuntu better. We are sorry that we do not always have the capacity to look at all reported bugs in a timely manner. There have been many changes in Ubuntu since that time you reported the bug and your problem may have been fixed with some of the updates. It would help us a lot if you could test it on a currently supported Ubuntu version. When you test it and it is still an issue, kindly upload the updated logs by running apport-collect <bug #> and any other logs that are relevant for this particular issue.
