Description Valorie Zimmerman 2010-11-14 06:38:59 UTC

Application: amarok (2.4-GIT)
KDE Platform Version: 4.5.3 (KDE 4.5.3)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-22-generic x86_64
Distribution: Ubuntu 10.10

-- Information about the crash:
- What I was doing when the application crashed: Had just saved a podcast which I found through the podcast directory. Found another RSS feed on the Internet, so was going to add that one in the Podcast area, but Amarok crashed. This the second time today that it has crashed when I selected Podcasts, so decided to file a bug.

Also running Firefox and Konversation.

-- Backtrace:

Comment 1 Myriam Schweingruber 2010-11-16 22:21:03 UTC

Confirmed. It sadly is not reproducible every time, I already filed this as bug 252622 and closed it since it works most of the time for me.

Comment 2 Valorie Zimmerman 2010-11-17 11:58:14 UTC

Oddly enough I haven't had another crash like this since I filed the bug. I don't know if updates fixed it, or chance, or what, but those two crashes within the hour were the last.

Comment 3 Myriam Schweingruber 2010-11-17 12:30:01 UTC

Closing as fixed for now, feel free to reopen if you can reproduce this crash.

Git commit e4c09dd3d207e7de4c9db2cd382746f98764c0dd by Bart Cerneels.
Committed on 05/06/2012 at 14:54.
Pushed by shanachie into branch 'master'.

Apply update from QtGroupingProxy.

commit 42febf5 from https://gitorious.org/qtgroupingproxy/qtgroupingproxy
	Call endRemoveRows in reverse order as begin...

	This is a hack, because beginRemoveRows() should always be followed
	by endRemoveRows() before the next remove. But since QAbstractItemView
	uses a stack to apply changes it works with those. Might break proxyies
	though.

Possible fix for SortFilterProxy crashes.
