Comment 1 Myriam Schweingruber 2010-12-22 14:55:02 UTC

Sorry, but your backtrace is not useful, as you are lacking debugging symbols. If you can reproduce this bug, please check here on how to get a valid backtrace:

Comment 2 Valentin Rusu 2010-12-22 23:03:33 UTC

Hello Myriam,
Please note that I used DrKonqi to submit this report. I used it to install the needed debugging symbols and It seemed happy when I submitted it, as it displayed the three stars. As I see, the Thread number 1 has plenty of KDE debugging info. Do you want me to install the libc debugging symbols also ?

Comment 3 Myriam Schweingruber 2010-12-24 11:39:53 UTC

The problem is you don't have debugging symbols for Amarok installed AFAICS.

Comment 4 tmax26 2011-01-08 17:49:42 UTC

Created attachment 55739 [details]
New crash information added by DrKonqi

amarok (2.3.2) on KDE Platform 4.5.5 (KDE 4.5.5) "release 1" using Qt 4.6.3

- What I was doing when the application crashed:

I was listening music with amark then I connect my sony walkman usb device and amarok crash, when I try to start again amarok until the sony walkman are connected it crash again.

Comment 5 Myriam Schweingruber 2011-01-08 19:20:32 UTC

Your backtrace shows your problem is caused by a problem with libmtp which is handled upstream, see also bug 236994
