Comment 3 Myriam Schweingruber 2010-11-16 22:28:30 UTC

Gyorgy, there is the nofork option, called --nofork, in one word.

I am 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.

Comment 4 Gyorgy Simon 2010-11-18 11:30:42 UTC

Hi,
Sorry for the useless trace, I read the document, and I check the
installed packaged what you mentioned, and yes, those are installed
finally, I cannot reproduce the crash while I installed the
libglib2.0-0-dbg package.

Thank you for your help.

Gyorgy

Comment 5 Myriam Schweingruber 2010-11-20 17:32:11 UTC

You are welcome, Gyorgy.

Ned, can you get a valid backtrace? The debug output is not really helpful.

New crash information added by DrKonqi

amarok (2.3.2) on KDE Platform 4.5.1 (KDE 4.5.1) using Qt 4.7.0

- What I was doing when the application crashed:Saving a new playlist, but when I press and hold the mouse over the 'Save Playlist' button and then release it, the playlist gets saved without crashing.

amarok (2.3.2) on KDE Platform 4.5.3 (KDE 4.5.3) using Qt 4.7.0

- What I was doing when the application crashed:

I tried to save the existing playlist using the "floppy-disk" button below the list.

Comment 8 Dennis Schridde 2010-11-22 15:39:45 UTC

P.S: Reproducible: every time
-> It seems currently impossible to save the existing playlist, which is kind of a show-stopper, because I cannot play different lists this way.

Comment 9 Myriam Schweingruber 2010-11-22 19:13:25 UTC

Dennis, you don't have the Amarok debugging packages installed, so your backtrace is not useful, sorry.
Anyway, this is a duplicate of bug 252597, thank you all for your feedback.

DrKonqi said the backtrace is perfect, gave 3 stars and didn't offer to install debug symbols, so I assumed it must be ok. Is this another bug (against DrKonqi), which I should report?

Comment 11 Myriam Schweingruber 2010-11-23 11:42:25 UTC

Did you check if you have the Amarok debug packages installed?
For this bug it is not relevant anymore, as the bug is solved in 2.4-git already.

Comment 12 oar.garuna 2010-11-24 08:02:37 UTC

I didn't know a stable version of 2.4 was out?

Comment 13 Myriam Schweingruber 2010-11-26 18:22:01 UTC

Read again, I didn't say a version of 2.4 was out, I said it was solved in 2.4-git which will be the next 2.4 version, git being the development version.
