Version: 2.5-git (using KDE 4.7.3) OS: Linux I updated amarok to current git master a175a7c501728928c786c23f241941c30a184809 and it crashes on start. It worked fine a week ago (with kde-4.7.2 & Qt-4.8-rc1) current KDE 4.7.3 & Qt 4.8-rc1. Reproducible: Always Steps to Reproduce: start it Actual Results: it crashes Expected Results: it should not crash Application: Amarok (amarok), signal: Aborted [Current thread is 1 (Thread 0x7f259b8217a0 (LWP 22189))] Thread 8 (Thread 0x7f2575818700 (LWP 22191)): #0 0x00007f2597f9f773 in __GI___poll (fds=<optimized out>, nfds=<optimized out>, timeout=<optimized out>) at ../sysdeps/unix/sysv/linux/poll.c:87 #1 0x00007f25916474b8 in g_main_context_iterate.isra.21 () from /usr/lib64/libglib-2.0.so.0 #2 0x00007f259164793b in g_main_context_iteration () from /usr/lib64/libglib-2.0.so.0 #3 0x00007f25989437d6 in QEventDispatcherGlib::processEvents (this=0x1a81fc0, flags=<optimized out>) at kernel/qeventdispatcher_glib.cpp:424 #4 0x00007f259890fb12 in QEventLoop::processEvents (this=<optimized out>, flags=...) at kernel/qeventloop.cpp:149 #5 0x00007f259890fd7f in QEventLoop::exec (this=0x7f2575817ce0, flags=...) at kernel/qeventloop.cpp:204 #6 0x00007f2598804690 in QThread::exec (this=<optimized out>) at thread/qthread.cpp:501 #7 0x00007f25988ed893 in QInotifyFileSystemWatcherEngine::run (this=0x1bcb940) at io/qfilesystemwatcher_inotify.cpp:248 #8 0x00007f259880750d in QThreadPrivate::start (arg=0x1bcb940) at thread/qthread_unix.cpp:298 #9 0x00007f258510225a in ??

I think this bug triggers only when Qt is build with debugging on. Reporters, you may want to work-around this by disabling debugging in Qt until this is properly fixed. Amarok devs should use debugging Qt builds to detect such errors early.

I was not quite right here, as pointed by Kevin Funk, QVector::at() is inline, so compiling amarok _without_ QT_NO_DEBUG should suffice to trigger this bug.
btw: I just installed amarok-2.4.3 again, with Qt-4.8rc1, and it works fine.
(In reply to comment #5) > btw: I just installed amarok-2.4.3 again, with Qt-4.8rc1, and it works fine. And what debug flags you have on Qt and Amarok? (assuming you use Gentoo)
CFLAGS contain -g FEATURES have splitdebug, but that doesn't matter debug useflag is not set, but it doesn't matter as the cflag enables it anyway Same flags for Qt/Amarok/the world, so all that matter is that amarok & Qt was compiled with debugsymbols

See https://bugs.kde.org/show_bug.cgi?id=279798#c14 and please read http://www.gentoo.org/proj/en/qa/backtraces.xml section "debug USE flag" carefully.
Ah yes, sorry. Qt was compiled with debug useflag, because I want to see asserts in all my programms. But only Qt has the debug useflag, not amarok. But now please don't tell me to disable this useflag, I know what I am doing :)
(In reply to comment #9) > Ah yes, sorry. > > Qt was compiled with debug useflag, because I want to see asserts in all my > programms. But only Qt has the debug useflag, not amarok. This means that you've worked around this bug, because it seems that it only happens when _Amarok_ is build with debug flag, as per comment 285720#c3 If you want to help us, you may perhaps want to build Amarok _with_ debug flag against Qt-4.8rc1 and report back whether it still asserts. > But now please don't tell me to disable this useflag, I know what I am doing :) Don't fear, we're well aware that we must support both debug & release Qt builds. :)
IF I find some time tonight or next week, I'll try bisecting to find which commit caused this. It shouldn't take too long since it didn't happen 1-2 weeks ago...
Created attachment 65294 [details] backtrace with debug useflag enabled I did enable debug useflag and re-emerged amarok-9999 but the backtrace looks the same

Thanks, that would be a huge help, Mikko. I guess it may be even automatised (see git bisect run), something like: file bisect-helper.sh: #!/bin/bash # ensure amarok is not running: pgrep amarok && echo "Amarok was running!" && exit 128 # build amarok and abort bisecting if it failed <build amarok somehow> || echo "build failed" && exit 128 amarok & sleep 60 if pgrep amarok; then # good, did not crash in a minute killall amarok exit 0 else # amarok did not survive a minute, probably crashed exit 1 fi

Thanks! Lets see what Bart says, as I dont understand the commit message, the purpose of the change and why it can make an assertion fail.
@ Bernd: if you still want to compile from master, just undo this little change: https://projects.kde.org/projects/extragear/multimedia/amarok/repository/diff/src/browsers/playlistbrowser/QtGroupingProxy.cpp?rev=e46a8ad0c52a50294de78c26fd8d3193e2467022&type=sbs and readd buildTree(); instead of the QTimer stuff. I've done it and it works fine on master.
The QTimer thing is to make sure the re-implementation of buildTree() is executed instead of the one from the base class.

Reopening as this is still present in Amarok 2.5 after upgrade.
Could it be the behavior of QTimer::singleShot() changed?

Xavier: your backtrace doesn't have debugging symbols, please install those or compile Amarok with the debug flag on.
(In reply to comment #28) > Xavier: your backtrace doesn't have debugging symbols, please install those or > compile Amarok with the debug flag on. Myriam, Xavier seems to be using Gentoo, debug flag has a different meaning there [1]. The always-correct (TM) formulation could be "compile Amarok with debugging symbols on". Xavier, please compile amarok with "-ggdb" somewhere in your CXXFLAGS and "splitdebug" in your FEATURES, for more info please read [1], which is an excellent debugging guide. You are _discouraged_ to enable the debug USE-flag for any software you don't develop yourself. In fact, I'm 99% sure you can work-around this bug by compiling kdelibs without debug flag.

I can confirm the problem. As a hotfix for me I've patched out the loading of playlists because I don't use them. The main playlist still works.

It also happen with Qt 4.8.1 here, but Qt is not at fault, its a bug in Amarok. Its related to Qt & amarok beeing build with asserts enabled. Which is normally a good thing to detect bugs early. (if you want to detect them and help the software getting better) In short a workaround is to build Qt and amarok with asserts disabled. The real bug is in amarok and needs to fixed.
Git commit d1a1c80370e4132c26fa636308822fdb3aa1b2e6 by Matěj Laitl. Committed on 05/05/2012 at 10:59. Pushed by laitl into branch 'master'. QtGroupingProxy: don't re-enter beginInsertRows() (crashfix) This should fix a nasty crash that was only reproducible when Qt was build with debugging assertions enabled. (and perhaps only if you have empty playlist providers) The fix is based on an assumption that addSourceRow() in QtGroupingProxy is only called from: a) buildTree(), which encompasses it in {begin/end}ResetModel() b) modelRowsInserted(), but that should be always preceeded by modelRowsAboutToBeInserted() that calls beginInsertRows() Bart, this is largely your code, is this correct?
