Reported using DrKonqi
Comment 1 Boerny 2011-01-10 18:45:56 UTC 
Bug affects me too.
Hada also a crash when listening to a podcast. Amarok crashed after some time.
Comment 2 Myriam Schweingruber 2011-01-10 19:10:37 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:

http://techbase.kde.org/Development/Tutorials/Debugging/How_to_create_useful_crash_reports

Since you are using Kubuntu, you will need amarok-dbg and phonon-dbg at least, ideally you should also have kdelibs5-dbg, libqt4-dbg and  libglib2.0-0-dbg. That should cover most of the crashes.

@Boerny: how do you know it is identical? Could you please paste your backtrace as well?
Comment 3 20120808_bugs.kde.org 2011-01-10 20:47:37 UTC 
Thanks for the feedback. I will be posted a corresponding backtrace after having installed the (missing) packages mentioned: <i>amarok-dbg libglib2.0-0-dbg phonon-dbg</i>.
Comment 4 20120808_bugs.kde.org 2011-01-11 19:28:16 UTC 
crashed twice 
first time drkonqi did not pick it up

started it again
noticed that the state of my podcasts (folders and links) was old (apparently only saves changes when closing amarok?)

continued organizing the podcasts, including creating new folders


amarok crashed. drkonqi showed up

here is the backtrace, which drkonqi showed as being worth three stars. ;)

Comment 5 Myriam Schweingruber 2011-01-11 20:12:48 UTC 
Thank you for the backtrace, it is indeed very good and shows this is a duplicate and already fixed in the upcoming Amarok 2.4, to be released later this month.

*** This bug has been marked as a duplicate of bug 256869 ***
