Description Jean-Christophe Dubois 2010-04-03 15:00:21 UTC
Application that crashed: amarok
Version of the application: 2.2.0
KDE Version: 4.3.5 (KDE 4.3.5)
Qt Version: 4.5.2
Operating System: Linux 2.6.31-20-generic i686
Distribution: Ubuntu 9.10

What I was doing when the application crashed:
Amarok was streaming an internet radio.

Meanwhile, I tired to browse some category on Jamendo through Amarok.

After some time Amarok died.

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

I'm quite sure this has been fixed, but I'm unable to find the correct dupe of this bug.

If it is still a problem in a recent version of Amarok please file a bug with an up2date backtrace.

I can reproduce this here with 2.4-git, but it seems to be a pulseazdio problem:

 pulse audio output debug: Pulse Close
Assertion 'o' failed at pulse/operation.c:128, function pa_operation_get_state(). Aborting.

No backtrace as it is a sgementation fault.

Could somebody else please test with current 2.4-git or Amarok 2.4 beta?
Comment 19 Stéphane Pontier 2010-12-14 17:23:03 UTC
The bug was happening and still happen with the git from today and pulseaudio was never installed on this computer.

Do you still get the same backtrace?
Comment 21 Stéphane Pontier 2010-12-15 14:01:25 UTC
Yes, I have this one. (I even tried with Jamendo service disabled and got the same problem and backtrace)

New crash information added by DrKonqi

I was searching for song titles on Jamendo, when Amarok crashed. I've just filed Bug 266065, but the related bugs suggested by Dr. Konqi didn't seem quite related, and were a bit old, too. So, on following crash, I waited for Dr. Konqi's suggestions again, and this time descriptions here seem more related. What I did: a simple search on Jamendo, which, as explained in Bug 266065, cannot be completed successfully. I don't have pulseaudio, either.

dirty hack, that somehow works...

Now, listen up developers, because I really do NOT know, what I am speaking about:

In CollectionTreeItemModelBase::populateChildren() some CollectionTreeItems are removed, containing the one (from d->compilationQueries, I think, but that may be of no relevance) that is later on used in CollectionTreeItemModelBase::queryDone(), which must lead to a segfault.

The patch fixes this, by not removing CollectionTreeItems, that are stuffed in d->runningQueries. This may be the wrong way, but it seems to work. (As a *quick* glance at the resulting behavior showed.) Someone, who really knows the Amarok sources should look into this patch, and if it is not a good solution, it may still be of help in fixing this bug.

PS: As I see it, this bug is not related to the Jamendo plugin. The problem also occurs with Magnatune.

Did you see the component this bug is filed under? It doesn't read Jamendo there, doesn't it?

amarok (2.4-GIT) on KDE Platform 4.6.1 (4.6.1) using Qt 4.7.0

- What I was doing when the application crashed: searching for a particular album on Jamendo

- Unusual behavior I noticed: I was on the webpage, so I know the file exists. Pasted in the exact name, and then Amarok crashed. These days, that means Plasma crashes too. What a drag.

Fix for "Crash when browsing a category on Jamendo"
This fix is consisent with the comments and stack traces in the bug
report but as I can't reproduce the crash I also can't verify the
fix.
Comment 43 Stéphane Pontier 2011-04-28 12:27:18 UTC
I tried the latest git version this morning, and tested by:
- launching amarok,
- searching some artist,
- erase some char and typing again in the search box

and amarok still crashed with the following backtrace:

Comment 44 Wolfgang Lorenz 2011-04-28 13:13:07 UTC
I posted a working patch about 2 month ago: https://git.reviewboard.kde.org/r/100723/

Could you test this one please?
Comment 45 Stéphane Pontier 2011-04-28 15:25:01 UTC
with this patch applied, I was able to do lot of searching and erasing during several minutes without a crash, before, it crashed after 2 or 3 "search/erase" cycle \o/
Comment 46 Myriam Schweingruber 2011-04-28 23:41:42 UTC
That is strange, I can't reproduce this here at all with the latest Amarok 2.4-git of today. 

Maybe you should try erasing pre-existing configuration files, in particular this one: $HOME/.kde/share/config/amarokrc (it might be $HOME/.kde4/share/config/amarokrc on some systems).
Comment 47 Stéphane Pontier 2011-04-29 12:45:18 UTC
I tried with the git version without the applied patch
started with my configuration file removed,
rescan my collection and played with search box in local collection:
  got no crash
I set again my preferences one by one playing with search box each time and figure out that as soon as I set the collection display to "style/artist/album" oposed to the default "artist/album", I got again the crash when playing with the search box.

After that, I installed again the  git version _with_ the patch from Wolfgang applied and no more crash whatever was the collection display ("style/artist/album" or "artist/album").

amarok (2.4.0) on KDE Platform 4.6.2 (4.6.2) using Qt 4.7.2

- What I was doing when the application crashed:

Selectted songs to play on Magnatune, and clicked play. Nothing happened. Clicked play again several times. Amarok then suddenly terminated.

Comment 52 Myriam Schweingruber 2011-05-21 17:11:29 UTC
Fixed by this commit:

Git commit 1e2bfd44b7509c5efe0fec328008ea72e7e999fd by Ralf Engels.
Committed on 20/05/2011 at 21:36.
Pushed by rengels into branch 'master'.

Crash when browsing a category [@ CollectionTreeItem::row]

patch for https://bugs.kde.org/show_bug.cgi?id=233170

When a query is started the Collections::QueryMaker* is stored in QHash<CollectionTreeItem*, Collections::QueryMaker*> runningQueries.

Now, when CollectionTreeItemModelBase::populateChildren deletes items CollectionTreeItemModelBase::itemAboutToBeDeleted is called, which in turn stops, disconnects and deletes the queryMaker associated with the item.

The problem occurs, if there is more than one queryMaker for the item, as will happen, when CollectionTreeItemModelBase::handleCompilations is called. In this case itemAboutToBeDeleted deletes only one queryMaker. The other one finishes normally, calls CollectionTreeItemModelBase::queryDone, which in turn calls CollectionTreeItem::row of a deleted item and Amarok crashes with a segfault.

The patch changes the runningQueries buffer to QMultiHash. So all queryMakers are kept and itemAboutToBeDeleted can stop them all.

I am not sure wether it's bind to your problems, but I'd similar issues and then I installed package linked on this page : http://amarok.kde.org/wiki/MP3
Since, no more crash.

I can't reproduce this with either Amarok 2.5 or 2.5-git of today, closing as fixed. Feel free to reopen if you can still reproduce this with Amarok 2.5 or later.
