Can somebody not using Mageia confirm this bug? Works fine for me on current git, Kubuntu 12.10 beta1

*** Bug 307669 has been marked as a duplicate of this bug. ***

All three people that can reproduce this use Mageia. Distibution / packaging problem most probably. Please report this to Mageia instead. You may want to try to build Amarok 2.6.0 from sources (uninstall all distro packages first) to test whether this is a distribution or packaging problem.

I am still getting this problem after building Amarok from sources (latest git master), installing it under /opt/amarok and then doing:

d=/opt/amarok
KDEDIRS="$d" "$d"/bin/amarok --debug

My Amarok build script is:

<<<
#!/bin/bash
test ! -e build && mkdir build
cd build
rm -f CMakeCache.txt
cmake -DCMAKE_INSTALL_PREFIX="/opt/amarok" \
    -DCMAKE_BUILD_TYPE=debugfull \
    ..
>>>

I am going to reopen this bug to get more info and proper investigation.

Some releated bug entries on bugs.mageia.org with some investigation:

* https://bugs.mageia.org/show_bug.cgi?id=7463

* https://bugs.mageia.org/show_bug.cgi?id=7748

And you are sure you get the same backtrace? I can't reproduce this here at all, wether with Amarok 2.6 final or 2.6-git, Kubuntu 12.10, KDE 4.9.2

Please provide a backtrace with the package you built from sources (of course this assumes you removed the Mageia package beforehand to make sure what starts is indeed the built package).

Created attachment 74774 [details]
Amarok GDB Backtrace after /usr/bin/amarok was removed.

Here is the gdb backtrace with the system-wide amarok removed. d=/opt/amarok (where I have installed it).

Please always paste backtraces inline, else those are not searchable.

Hi Shloni,
removing /usr/bin/amarok and setting just KDEDIRS is not enough. Please remove the whole Amarok distribution package, e.g. so that there are no
/usr/lib64/libamarok*
/usr/lib64/kde4/amarok_*
and set also LD_LIBRARY_PATH as appropriata. Please refer to http://blogs.fsfe.org/myriam/2009/09/26/compiling-amarok-from-git-locally-full-summary/ for complete instructions.

Also, the backtrace emits a lot of warnings like
warning: the debug information found in "/usr/lib/debug/usr/lib64/libsoprano.so.4.3.0.debug" does not match "/lib64/libsoprano.so.4" (CRC mismatch). -- which looks like an indication that Mageia's package manager screwed up keeping binaries and debugging information in sync.

When creating backtraces using gdb, please do them as follows:
# wait for crash
(gdb) set height 0
(gdb) thread apply all bt 20

On the other hand, I'm still pretty convinced this is a bug on the distribution side. No-one with other distro reported the crash and Megeia makes only a small portion of our users.

Also please note that the discussion on https://bugs.mageia.org/show_bug.cgi?id=7748 is completely misleading: yes, stopping udisks may "prevent" the crash, but it just prevents Amarok from running a lot of code incl. code in MountPointManager. This is like preventing the crash by not turning on your computer.

Futhermore, it is crashing deeply in Qt, namely in QThreadData destructor triggered by QObjectPrivate destructor triggered by QScopedPointer destructor triggered by QTextStream destructor triggered by QDebug::Stream destructor triggered by QDebug destructor, which is called by compiler-generated code. There's little Amarok can affect so deep inside Qt (unless this is a memory corruption bug). I would perhaps suggest compiling and using your own Qt.

OK, thanks for the tip.

I see.

I compiled Qt from source (without any patches) using «./configure --prefix="$HOME/apps/qt-4.8.x" -opensource -confirm-license» and installed it and ran Amarok using:

<<<<
#!/bin/bash
d=/opt/amarok
export LD_LIBRARY_PATH="$HOME/apps/qt-4.8.x/lib:$d/lib64"
export KDEDIRS="$d"
"$d"/bin/amarok
>>>>

It runs fine at first, after I move away ~/.kde4/share/apps/amarok but crashes: 1. On exit. 2. Immediately after the first time. I verified using ldd that the Qt libraries from ~/apps/qt-4.8.x/lib are loaded.

No longed needs info.

Hmm, strange. Please paste the backtrace with your own Qt. You'll may have to recompile Qt in debugging mode or with -ggdb in CXXFLAGS: just check that line numbers are there in the Qt part of the backtrace. It may be also beneficial if you compile Qt without optimisations (-O0).

- What I was doing when the application crashed:
With Mageia3 alpha3
I tried to open a file cantique.wav
I hear the default sound but not my file.
I tried to restart, again and again: no sound.

- Custom settings of the application:
Standard installation of mageia without anything specific.

I received this crash as well.  I removed my ~/.kde/ amarok app and config files and restarted.  It opened with these errors on the terminal:

Failed enumerating UDisks2 objects: "org.freedesktop.DBus.Error.Disconnected" 
 "Not connected to D-Bus server" 
virtual QStringList Solid::Backends::UPower::UPowerManager::allDevices()  error:  "org.freedesktop.DBus.Error.Disconnected"

I was able to scan my collection without a problem.  Played a song without a problem.  Then :
- I opened the settings dialogue
- Enabled "write statistics to files"
- Disabled a couple plugins
- Enabled LastFM
(I believe that was all I did)
- Hit OK  ==> CRASH

I have the full debug saved if requested, here's thread 1:

Megeia should fix their Qt. Really.

Please reopen only if you are able to reproduce in a different distribution. The last backtrace contains *no* Amarok functions, just Qt, a bit of kdeui and a bit of liboxygenstyle.

I am not going to reopen it (for now), but I wish to note that in comment 
https://bugs.kde.org/show_bug.cgi?id=306520#c18 I compiled Qt from source, without optimisations onto a prefix, and set LD_LIBRARY_PATH/etc. accordingly and Amarok still crashes. So it is possible the problem is not in the Mageia Qt, but rather in the way that Amarok is using it. It could also be a downstream patch on a different distribution, or a gcc/g++ bug or whatever. Please read the entire thread.

*** Bug 312133 has been marked as a duplicate of this bug. ***

This bug is not yet resolved.  It appears the problem is one of static vs dynamic linking for /lib64/libmysqld.so, but this has not yet been demonstrated nor corrected.

As a work-around to obtain limited functionality, you can 
rm -rf ~/.kde4/share/apps/amarok/mysqle/amarok 
or perhaps rm -rf ~/.kde4/share/apps/amarok/mysqle.  If that does not work, 
rm -rf ~/.kde4/share/apps/amarok should do the job, at the cost of any data already collected.

In all cases, when you remove some of the files under ~/kde4/share/apps/amarok, you can expect it to take amarok perhaps a few minutes to rebuild what it needs.  If all are removed, you will have to reconfigure settings for amarok.

You will probably have to go through the work-around exercise each time you start amarok.

> This bug is not yet resolved.

Jim, RESOLVED DOWNSTREAM means that the problem is not on the Amarok side. Yes, it is perhaps not yet resolved, but its bug reports belongs to Mageia bug reposting site, not here.

How do you know?

THIS IS NOT ENDORSED OR RECOMMENDED BY AMAROK DEVELOPERS IN ANY WAY.

Jim, if you think the problem is linking libmysqld.so, perhaps the work-around is to use external MySQL database?

Much easier work-around:
1. rm -rf /
2. Install any other Linux distribution
[/pun]

I'm reopening this bug, because as I demonstrated, and tried out, Amarok that uses a Qt which was compiled from source, with debugging symbols and without any optimisations still crashes there. So trying to pinpoint it to the Mageia's Qt is not constructive - it is caused by some other factor. If you wish to resolve it as DOWNSTREAM, then pinpoint the exact reason.

Shlomi: pleas don't this is definitely NOT an Amarok bug as nobody else can reproduce that but people using Mageia, so it must be a downstream problem. Please do not reopen this report, instead check with Mageia, something is wrong in their Qt packages.

I've already did the LD_LIBRARY_PATH / KDEDIRS / etc. dance with a Qt compiled from source and verified that this is what Amarok is using, so the problem is not with the Mageia Qt or not exclusively with it. Not opening this bug, and I'll try to investigate it.
