Description chris 2014-06-06 08:38:25 UTC 
whenever I try to adjust the equalizer, this causes a crash, the ticking the box active, resets the current song, every attempt to move a cursor causes crash.

Reproducible: Always

Steps to Reproduce:
1.Tools menu> equalizer
2.active check box
3.move any cuseur
Actual Results:  
systematic crash

Expected Results:  
adjust the musical frequencies
Comment 1 chris 2014-06-06 08:42:54 UTC 
clicking cancel the equalizer window, the song restarts at the beginning
Comment 2 Myriam Schweingruber 2014-06-06 17:25:24 UTC 
We need a backtrace for the crash. Please make sure to install all necessary debugging symbols for Amarok and its dependencies, and reproduce the crash. For more information, please check here:  https://community.kde.org/Amarok/Development/DebuggingHowTo#Getting_a_Backtrace

backtrace in gdb

The first message (Attempting to add QLayout) is displayed when the equalizer is enabled (and the song is reset to the begining). The crash occurs when a cursor is moved.
Comment 4 Myriam Schweingruber 2014-06-28 17:35:12 UTC 
Don't you get a backtrace with Dr.Konqi? Your gdb backtrace is sadly quite useless, I don't see any relation to Amarok, and it appears way too short short for a proper backtrace...
Comment 5 Myriam Schweingruber 2014-08-10 19:32:33 UTC 
Closing for lack of feedback. Please feel free to reopen this report if you can provide the requested information.

crash report from terminal in debug mode

This is from starting Amarok in debug mode.

That is not a backtrace, please see comment #2 on how to get a backtrace. Also please paste the resulting backtrace in line, else it is not searchable.
Comment 8 Myriam Schweingruber 2015-02-24 18:18:10 UTC 
Setting status correctly, waiting for backtrace.
Comment 9 Beo Enduser 2015-02-24 18:38:42 UTC 
I'm sorry, I can't get the backtrace to work. I do have the packages listed, I've even tried this command as listed on the page you gave:
gdb `which amarok` -p `pidof amarok`
but it is just giving me syntax error messages. I can't get this to work.
Please be assured though, that the bug does exist.

I'm running Kubuntu 14.04
with:
Qt: 4.8.6
KDE Development Platform: 4.13.3
Amarok: 2.8.0
Comment 10 Myriam Schweingruber 2015-02-24 18:54:45 UTC 
What exact syntax errors do you get?
Comment 11 Beo Enduser 2015-02-24 19:18:42 UTC 
This (pasted right from that page from comment #2):
gdb `which amarok` -p `pidof amarok`
gdb: option '--p' requires an argument
Use `gdb --help' for a complete list of options.
$  (gdb) thread apply all bt
bash: syntax error near unexpected token `thread'

and this when trying to get it to run:
(gdb) run
Starting program:  
No executable file specified.
Use the "file" or "exec-file" command.

The only command it seems to understand is quit.
Comment 12 Myriam Schweingruber 2015-02-24 21:24:47 UTC 
Right, that is indeed a problem :) 
I will adapt the wiki to make this more clear, the entry 'pidof amarok' needs to be replaced by the PID number of the amarok process. You can see the PID number for example by running the command "top".

There is a simpler way, try the following lines, one after the other:

gdb amarok
run -d --nofork

This will start amarok in a much slower way, but you can then proceed to do the steps to provoke the crash. Once the crash happens, in the same console window, enter this:

thread apply all bt

We need the part that is printed after this command.

Thank you very much, Myriam!
I will try that next time I am on my linux box.

Comment 14 Beo Enduser 2015-02-25 19:01:23 UTC 
ok, here is what happened (I hope this is clear)
Still no backtrace ability, sadly....

1st time when I typed gdb amarok, it gave me this:

done.

1st attempt: gdb was running, then I started Amarok normally because run -d –nofork didn't do anything the first time I tried it. 

This is the part, as far as I can figure that refers to the time of the crash:

2nd time I tried it, (the run -d --nofork command worked this time!) this is the last bit:

Then I typed:
threat apply all bt
it gave me:

Comment 15 Myriam Schweingruber 2015-02-25 19:43:10 UTC 
you mistyped, the command is

Backtrace 1

1st backtrace -- started my song, opened the equalizer, activated it then moved a slider, Amarok froze.

2nd backtrace

2nd test -- this time I tried using one of the presets.
Comment 19 Beo Enduser 2015-02-26 22:09:44 UTC 
Ok, I finally have 2 backtraces for you. Both times, Amarok just froze, it's window didn't close as it had when I first reported it to you.
 
Test 1: I tried to move the equalizer slider.
2nd test: I tried to use a preset.

Let me know if this is good.
Comment 20 Myriam Schweingruber 2015-02-27 12:05:23 UTC 
Could you please paste the backtraces inline next time? Searching strings in attachments is not possible in the search options of bugzilla. See also my comment #7...

Comment 21 Myriam Schweingruber 2015-02-27 12:09:10 UTC 
As seen in the backtrace, the crash is most likely with the phonon-backend-gstreamer, or the gstreamer library. Please make sure to get debugging symbols for gstreamer, pluseaudio and phonon and its backend so we can sort this out.

Reassigning to the phonon-backend-gstreamer
Comment 22 Beo Enduser 2015-03-09 16:00:12 UTC 
My son-law made another backtrace. I'm pretty sure he got all the libraries. 

So, I will paste the report here.

Comment 23 Myriam Schweingruber 2015-03-09 16:11:21 UTC 
Of course you have the libraries, as those are needed to run the program, but you don't have debugging symbols installed for the gstreamer library, phonon-backend-gstreamer, Phonon and Pulseaudio. Search for the packages with the extension -dbg.
Comment 24 Vangelis 2015-04-26 15:37:40 UTC 
Here is backtrace for the same problem. Reproducable all the time.

Comment 25 Myriam Schweingruber 2015-04-26 18:10:36 UTC 
@Vangelis: how did you generate that backtrace? Would be nice to have the header and ideally one generated by Dr. Konqi, so far I can only see gstreamer related threads (as in gstreamer library, not phonon related). 
Also you don't tell your system specifications, that is why the header of the backtrace is important as it sums up the system specs (at least Dr. Konqi does)
Comment 26 Vangelis 2015-04-26 18:30:21 UTC 
* I installed all of the debug symbols (I actually had to repeat quite sometimes in order to make sure that all of the debug symbols are installed)
* I ran `gdb --args amarok -d --nofork`
* I started playing a song
* Opened the equilizer
* when I touched the vertical bars, amarok crashed
* From the gdb window, I typed `thread apply all bt`
* I pasted the output here.

Unfortunately, Dr. Konqi is not coming up, and I get a message "Unable to start Dr. Konqi".

My system is Kubuntu 14.04 fully up to date as of today.

Comment 27 Myriam Schweingruber 2015-04-26 18:51:31 UTC 
Right, of course Dr. Konqi will not run if you start Amarok in a gdb environment. you need to run Amarok just normally :)

FWIW: currently using Amarok from git v2.8.0-459-ged0b96e on Kubuntu 14.10, KDE 4.14.2 which uses a much more recent Phonon-backend-gstreamer than you do: I can't reproduce this bug at all, never seen a crash.

I presume this is fixed with the gstreamer 1.x libraries used in phonon-backend-gstreamer starting with version 4.7.90 (aka 4.8 beta) anyway.
Comment 28 Vangelis 2015-04-26 19:24:25 UTC 
Dr. Konqi was not coming up anyway, that's why I used gdb :)

If it's fixed in a newer version, then I guess it's fixed.

I actually installed the following packages from the vivid repository, but I still got the crash.

phonon-backend-gstreamer_4.8.2-0ubuntu1_amd64.deb
phonon-backend-gstreamer-common_4.8.2-0ubuntu1_amd64.deb
libglib2.0-0_2.44.0-1ubuntu3_amd64.deb
libgstreamer-plugins-good1.0-0_1.4.5-1ubuntu2_amd64.deb

Unfortunately, I could not "easily" install the dbg packages (many dependencies, that would mess up my whole system) to get another proper backtrace, so I reverted back to the "trusty" versions.
Comment 29 Myriam Schweingruber 2015-04-26 19:44:51 UTC 
You installed the 15.04-packages into 14.04? Bad idea, as those are not compiled against the correct libraries of KDE and Qt anyway, you should not do that.

AFAIK the Kubuntu backports PPA and updates PPA is the only way to get newer packages in a previous release, using packages from a later release is never a good idea.

Also: if you use a newer Phonon backend you also need to change all the gstreamer libraires and plugins, as the 0.10.x plugins are incompatible and need to be removed.
Comment 30 peddanet 2016-10-06 19:06:53 UTC 
Hi, problem still persists. :-(

My system: Ubuntu 14.04 Unity (not KDE), Amarok 2.8.0,  KDE 4.13.3

Problem just occurs every time, only after activating equalizer, and changing the equalizer tabs AFTER one song was played or is being played. So it could have something to do with changing the equalizer bands while there has been played a song after start,.

If you just start the equalizer, you can adjust it and save it. After restart it will play with these settings. Then again it crashes, when changing the equalizer tabs, not so with "Default button", which works. Dr. Konqi is not starting, maybe because of running Unity. Debug packages for phonon-backend-gstreamer, amarok-dbg and pulseaudio is installed. Which log do you need (and where can I find it)?

Now it's getting really weird, after doing the above mentioned steps (changing and saving without playing a song and quitting) for some time, the error was not reproducible, the first time today!! Now I can change the equalizer whenever I want. Earlier in the day I skipped that wikipedia thing, if this might be of interest. But I worked without restarts of the system, and there seems no connection.  I 'll try to accept it ;-)
Comment 32 Andrew Crouthamel 2018-09-19 14:26:55 UTC 
This bug has had its resolution changed, but accidentally has been left in NEEDSINFO status. I am thus closing this bug and setting the status as RESOLVED to reflect the resolution change.
