Description uberprugelknabe 2011-09-26 22:49:36 UTC

Application: amarok (2.4-GIT)
KDE Platform Version: 4.6.2 (4.6.2)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-11-generic x86_64
Distribution: Ubuntu 11.04

-- Information about the crash:
- What I was doing when the application crashed:

Normal playback using the xine backend for phonon which has been causing problems lately as amarok is completely mute using it (doesn't appear in the PulseAudio Volume Control on the playback tab). After a little while amarok crashes. Debug information in the terminal is the following:

QSocketNotifier: Invalid socket 47 and type 'Read', disabling...
KCrash: Application 'amarok' crashing...
KCrash: Attempting to start /usr/lib/kde4/libexec/drkonqi from kdeinit
sock_file=/home/ogmundur/.kde/socket-Augustiner/kdeinit4__0
82	../sysdeps/unix/syscall-template.S: No such file or directory.
Application asked to unregister timer 0x49000006 which is not registered in this thread. Fix application.

Using the VLC Backend audio is played but amarok also crashes after a little while.

The crash can be reproduced every time.

-- Backtrace:
Application: Amarok (amarok), signal: Segmentation fault

Comment 1 Myriam Schweingruber 2011-09-27 06:19:47 UTC

FWIW, I strongly suggest you use either the phonon gstreamer or vlc backend. the xine backend is deprecated and unmaintained.

Which applets are active in the Context View? Is this crash reproducible? Then please provide steps how to reproduce it.

amarok (2.4-GIT) on KDE Platform 4.7.1 (4.7.1) using Qt 4.7.4

Just had the same crash here, starting a mp3 file, using the gstreamer backend 4.5.1, on Kubuntu 11.10 beta2, Amarok current git.

Comment 3 Myriam Schweingruber 2011-09-27 20:29:51 UTC

The crash is sadly not reproducible, so far I only had that once. A possible workaround is to disable animations in the Context View.

Comment 4 Daniel Faust 2011-09-28 12:16:32 UTC

I just ran into this bug after pulling the latest amarok from git and doing a dist upgrade. Qt was 4.7.3 i think, now it's 4.7.4.
My distribution is opensuse 11.4.
I can reproduce this crash every time, disabling the collapse animation avoids it.

Changing priority.

Comment 6 uberprugelknabe 2011-09-28 22:16:51 UTC

OK, switched to the VLC backend (version 0.3.2) and disabled the context applet collapse animations and now the crashes no longer occur (yay!). Am using amarok from git and KDE 4.6.2. My distribution is Ubuntu 11.04.

amarok (2.4-GIT) on KDE Platform 4.7.2 (4.7.2) using Qt 4.7.4

I've the same problem here. I'm using gstreamer.

Amarok crash when we start playng a song.

Normally this problem appear if we play a flac file.

I'm getting the same crash using the gstreamer backend here.  No pulseaudio; just regular old ALSA, thanks.  I noticed it seems to happen around the time it switches songs, leading me to believe it may be related to the OSD (a race condition or something).  I'd test further, but I'm supposed to be doing work right now. ;)
