Description robert marshall 2012-08-12 11:09:04 UTC
I'm not able to generate this bug reliably but the typical environment is that I've generated an APG and then I add the tracks from a cd to the end of the list. When the whole play list completes if I then try to generate another APG amarok will crash.

Reproducible: Always

Steps to Reproduce:
1. Generate APG, insert cd add all cd tracks to the play list
2.Let the playlist run to completion
3.Leave amarok for a few minutes (not certain that this is essential)
4. Generate another APG - amarok will crash
Actual Results:  
amarok crashes

Expected Results:  
It shouldn't crash

The drkonq app gives me the following line for the stacktrace
    Application: Amarok (amarok), signal: Segmentation fault
looking as if the call stack has been totally corrupted? (I have amarok-dbg installed)

The last few lines in my .xsession-errors reads:
HTTP POST:  QUrl( "http://post2.audioscrobbler.com:80/protocol_1.2" )  "s=6cffdc038b4a45b889bf69af08cb45fa&a[0]=Berg%2C%20Alban&t[0]=Violinkonzert%20f%C3%BCr%20Louis%20Krasner%20-%20Allegro%20-%20Adagio&i[0]=1344754667&o[0]=P&r[0]=&l[0]=1019&b[0]=Orchesterwerke%20%28Venzago%2C%20Soli%2C%20G%C3%B6terborger%20Symphoniker%29&n[0]=0&m[0]="

If I rerun amarok from this point and then immediately generate an APG it will crash every time but as at this point the cd tracks in the playlist aren't refreshed I'm not sure that this is useful (it may already be in a undesirable state!) - I can add some information to the bug list if you need.

The apg I'm using is

        <constraint comparison="1" length="30" type="PlaylistLength" strictness="1"/>
      </group>
    </constrainttree>
  </generatorpreset>
I'll add the playlist which has just completed when I run APG as an attachment as I don't think it will be needed for searching.

From another crash in the same circumstances, attaching gdb to amarok first

A debugging session is active.

	Inferior 1 [process 9340] will be detached.

My guess at the cause is that I have  composer contraints in the APG I'm running

Because you don't have all debugging symbols installed, see the ?? for your nvidia drivers?

No, that has nothing to do with it, the problem is in Amarok::PrettyTreeView::drawRow, which is quite different from the previous backtrace you posted, so this is yet another crash.

Amarok 2.6 has been release and it is available in the backports PPA for 12.04, could you please update and try again?
Comment 6 robert marshall 2012-08-14 14:13:49 UTC
And with 2.6

I've generated a core file from gdb so I can dig around in it further if needed!
Comment 7 Soren Harward 2012-08-14 14:43:08 UTC
I've never tried using the APG with CD tracks (I think Amarok 2 didn't even support CD tracks while I was developing the APG), so it well could be a bug in the APG, or a bug in Meta::Track that's triggered by the APG.

Do the following steps produce a crash for you?

- Restart Amarok
- Insert CD
- Wait a few seconds for Amarok to pull in metadata for CD
- Run the APG

Also, can you please add the tracks from the CD to a playlist, export that playlist, and post it as an attachment?  I'd like to see what metadata Amarok has for the CD tracks that are causing the problem.

Thanks.
Comment 8 robert marshall 2012-08-14 15:40:48 UTC
Created attachment 73162 [details]
playlist containing only cd tracks
Comment 9 robert marshall 2012-08-14 15:41:09 UTC
Yes I get a crash with that recipe. I wasn't consciously using APG with cd tracks it just happened that a cd was in the drive when I originally got this crash.
The original attachment has cd tracks included in it, but I'll add one with just cd tracks
Comment 10 Myriam Schweingruber 2012-09-12 09:00:58 UTC
Setting status correctly.
Comment 11 Mayank Madan 2012-12-19 14:12:40 UTC
I ran Automatic playlist generator then after the playlist was finished i ran the APG again and it crashed(I inserted the CD in the beginning)
Using v2.6.90-26-gbcdd84c
Comment 12 Myriam Schweingruber 2012-12-21 10:14:27 UTC
Confirmed on latest git.
