Description Frank Steinmetzger 2011-04-26 01:46:06 UTC 
Application: amarok (2.4-GIT)
KDE Platform Version: 4.6.2 (4.6.2)
Qt Version: 4.7.2
Operating System: Linux 2.6.36-gentoo-r8 i686
Distribution (Platform): Gentoo Packages

-- Information about the crash:
- What I was doing when the application crashed:
I had the Cover Manager open to look for albums without cover art. I found one, filtered the collection for it so I could drag one of its tracks to kid3 for editing. In kid3 I saved new tags and an image file for the cover. Lastly I triggered a collection rescan, boom.

I added covers to a number of albums yesterday the same way without a problem, the only difference was that the Cover Browser was not open. For confirmation I just did the same thing about half a dozen more times, but the crash did not reoccur.

KDE 4.6.2, Amarok was built from GIT on 21. April.

The crash does not seem to be reproducible.

The crash was not in Amarok, but in Qt, but if it is not reproducible there is no use reporting it anyway as we can't do anything, sorry.
Comment 2 Frank Steinmetzger 2011-04-26 14:04:14 UTC 
Eventually I got it again, but it took a while and I lost the trace because KMail crashed Kontact when I wanted to look at this bug again afterwards. I don't suppose I can file Qt bugs here so they are relayed appropriately? (I’m always hesitant to create new accounts that I’m only going to use once or twice a year).
Comment 3 Myriam Schweingruber 2011-04-26 15:11:30 UTC 
Qt bugs need to be reproducible reliably and one has to create a demo case, so for a plain user it's not really doable. 

In any case, Qt bugs need to be reported upstream here: http://bugreports.qt.nokia.com
Comment 4 Christoph Feck 2011-05-02 14:08:34 UTC 
> The crash was not in Amarok, but in Qt

In the backtrace, lines #19 and #20 clearly shows that the stack is corrupted. Memory corruption could have happened by a different thread or any other bug. It certainly isn't a Qt bug.

If you can reproduce this issue, please provide a valgrind and hellgrind log with full debug information enabled.

Comment 6 Myriam Schweingruber 2011-08-07 10:25:28 UTC 
Robert, this report is about the 2.4-git version from may which is ahead of your version. Please upgrade to Amarok 2.4.1 or 2.4.3 and check again.
