Description Benjamin M 2010-09-11 19:09:40 UTC

Version:           2.3.1 (using KDE 4.5.1) 
OS:                Linux

As detailed on the forums here ( http://forum.kde.org/viewtopic.php?f=115&t=90127 ), 
I have been having frequent system freezes recently that also killed Amarok. The next time I start Amarok, it crashes on me with the below output. I can restart it without problems, but scrobbling won't work anymore. This is not a problem with last.fm login information or kwallet, it is most likely related to this crash (at least there is a correlation). 
While scrobbling doesn't work anymore, liking a song still does and shows up on the website. Amarok keeps all my login information. Once I manually test-login from the options window of the last.fm service, the like-button disappears from Amarok, but is restored at the next program start. 

At some point, scrobbling works again, but I haven't figured out what exactly causes it to work again. 


Reproducible: Always

Steps to Reproduce:
1. System crashes while Amarok is running for reasons yet undetermined, but possibly kwin, flash or graphics driver related. Hence Amarok dies too. 
2. Restart computer and start Amarok. It crashes (I think every time). 
3. Restart Amarok to experience described behavior. 

Actual Results:  
1. Amarok crashes when started after system crash that killed it. 
2. Scrobbling to last.fm stops working, liking songs still works. 
3. Like-buttons disappear after I test the login. 

Expected Results:  
No crash; scrobbling shouldn't be affected, etc. 

Here is the crash log:

Comment 1 Myriam Schweingruber 2010-09-12 15:08:00 UTC

This is a duplicate crash of the one in bug 245513. Please see comment #27 and try again, this should be solved already.

Comment 2 Benjamin M 2010-09-12 16:53:14 UTC

The only applet mentioned in #27 that I use would be the album applet, so I guess I will have to disable it to prevent the crash (the only other applet I use wikipedia). 

But does that also mean that the last.fm problem would be fixed? It seems this is a seperate problem triggered by the crash, but you didn't say if it is also caused by the crash. 
I don't care about the crash and I can wait until 2.3.2, but I would like scrobbling to work...

Comment 3 Myriam Schweingruber 2010-09-12 22:00:06 UTC

Sorry, I might have sounded as if this scrobbling problem were solved, but only intended to give you a workaround to prevent the crash.

The problem is to find out why the scrobbling doesn't work anymore after a crash, which would need a console output. Could you please try reproducing the crash and start Amarok in a terminal twice with the following options: -d --nofork
You need to run it twice to have the debugging output enabled, so maybe do this first, then, try reproducing the crash

Comment 4 Benjamin M 2010-09-13 04:13:19 UTC

Ok, thank you for the clarification! I will provide you with the log as soon as one little obstacle is out of the way. 
Konsole seems to display only a limited amount of lines, so the beginning of the output is cut off, if I am not mistaken. This happened even the second time I tried despite my checking of the third option (unlimited something) in the fourth tab from the left in the konsole profile settings (which I thought would fix it). So I guess it would help if somebody knew how to turn off this limitation.

Comment 5 Myriam Schweingruber 2010-09-13 12:16:48 UTC

Well, why don't you redirect the output to a text file instead of copying it from konsole?

Comment 6 Benjamin M 2010-09-21 18:44:19 UTC

I'm sorry, I tried to not be a noob about it and just find out how to do it by myself. The command string seems to be "amarok -d --nofork > amarok.txt" (for an output into the textfile "amarok.txt"), but the file stays empty. I'm gonna need some assistance with this... Sorry for the hassle.

Comment 7 Myriam Schweingruber 2010-09-21 21:43:39 UTC

To redirect the output, try this:

amarok -d --nofork 2> amarok_output.txt

Comment 8 Myriam Schweingruber 2010-12-14 00:18:14 UTC

Any news on this? Amarok 2.3.2 has been released in the mean time and you could also test Amarok 2.4 beta

Comment 9 Benjamin M 2010-12-14 21:52:34 UTC

Sorry, I had gotten sidetracked from this. Basically, the bug wasn't around anymore after the 2.3.2 upgrade. 

Thanks anyway! :-)

Comment 10 Myriam Schweingruber 2010-12-14 22:49:45 UTC

Thank you for the feedback.
