Application: akregator (1.6.5) KDE Platform Version: 4.4.5 (KDE 4.4.5) (Compiled from sources) Qt Version: 4.6.3 Operating System: Linux 2.6.34-gentoo-r2 x86_64 Distribution: "Gentoo Base System release 2.0.1" -- Information about the crash: Due to a power outage few days ago some files on my HDD got corrupted. Among them seems to be ~/.kde4/share/apps/akregator/data/feeds.opml and now Akregator complains about invalid default feedlist but when I try to create a new one via Feed -> New Folder it segfaults each time. If it matters some other files might have been lost/damaged too so it might not be necessarily just feeds.opml being empty. The crash can be reproduced every time. -- Backtrace: Application: Akregator (akregator), signal: Segmentation fault [KCrash Handler] #5 Akregator::FeedList::allFeedsFolder (this=0x0) at /usr/src/debug/kde-base/akregator-4.4.5/akregator-4.4.5/akregator/src/feedlist.cpp:412 #6 0x00007fbdcf09759d in Akregator::MainWidget::slotFeedAddGroup (this=0x1c289b0) at /usr/src/debug/kde-base/akregator-4.4.5/akregator-4.4.5/akregator/src/mainwidget.cpp:668 #7 0x00007fbdcf09df95 in Akregator::MainWidget::qt_metacall (this=0x1c289b0, _c=QMetaObject::InvokeMetaMethod, _id=<value optimized out>, _a=0x7fffc06274c0) at /usr/src/debug/kde-base/akregator-4.4.5/akregator-4.4.5_build/akregator/src/mainwidget.moc:168 #8 0x00007fbddf8c4316 in QMetaObject::activate (sender=0x1b51de0, m=<value optimized out>, local_signal_index=<value optimized out>, argv=0x1) at kernel/qobject.cpp:3287 #9 0x00007fbdde9f1432 in QAction::triggered (this=0x0, _t1=false) at .moc/release-shared/moc_qaction.cpp:263 #10 0x00007fbdde9f349b in QAction::activate (this=0x1b51de0, event=<value optimized out>) at kernel/qaction.cpp:1255 #11 0x00007fbddee2e691 in QMenuPrivate::activateCausedStack (this=<value optimized out>, causedStack=..., action=0x1b51de0, action_e=QAction::Trigger, self=true) at widgets/qmenu.cpp:1002 #12 0x00007fbddee34202 in QMenuPrivate::activateAction (this=0x1e1ddf0, action=0x1b51de0, action_e=QAction::Trigger, self=<value optimized out>) at widgets/qmenu.cpp:1094 #13 0x00007fbde037354e in KMenu::mouseReleaseEvent (this=0x1e37220, e=0x0) at /usr/src/debug/kde-base/kdelibs-4.4.5/kdelibs-4.4.5/kdeui/widgets/kmenu.cpp:471 #14 0x00007fbddea4d701 in QWidget::event (this=0x1e37220, event=0x7fffc0628290) at kernel/qwidget.cpp:8044 #15 0x00007fbddee363cb in QMenu::event (this=0x1e37220, e=0x7fffc0628290) at widgets/qmenu.cpp:2421 #16 0x00007fbdde9f762c in QApplicationPrivate::notify_helper (this=0x1a65c30, receiver=0x1e37220, e=0x7fffc0628290) at kernel/qapplication.cpp:4302 #17 0x00007fbdde9fe35b in QApplication::notify (this=0x7fffc0628d90, receiver=0x1e37220, e=0x7fffc0628290) at kernel/qapplication.cpp:3867 #18 0x00007fbde02973e6 in KApplication::notify (this=0x7fffc0628d90, receiver=0x1e37220, event=0x7fffc0628290) at /usr/src/debug/kde-base/kdelibs-4.4.5/kdelibs-4.4.5/kdeui/kernel/kapplication.cpp:302 #19 0x00007fbddf8b114b in QCoreApplication::notifyInternal (this=0x7fffc0628d90, receiver=0x1e37220, event=0x7fffc0628290) at kernel/qcoreapplication.cpp:726 #20 0x00007fbdde9fd482 in QCoreApplication::sendEvent (receiver=0x1e37220, event=0x7fffc0628290, alienWidget=0x0, nativeWidget=0x1e37220, buttonDown=<value optimized out>, lastMouseReceiver=<value optimized out>, spontaneous=true) at ../../include/QtCore/../../src/corelib/kernel/qcoreapplication.h:215 #21 QApplicationPrivate::sendMouseEvent (receiver=0x1e37220, event=0x7fffc0628290, alienWidget=0x0, nativeWidget=0x1e37220, buttonDown=<value optimized out>, lastMouseReceiver=<value optimized out>, spontaneous=true) at kernel/qapplication.cpp:2967 #22 0x00007fbddea7dc7e in QETWidget::translateMouseEvent (this=0x1e37220, event=<value optimized out>) at kernel/qapplication_x11.cpp:4314 #23 0x00007fbddea7c49a in QApplication::x11ProcessEvent (this=<value optimized out>, event=0x7fffc0628a10) at kernel/qapplication_x11.cpp:3513 #24 0x00007fbddeaa6442 in x11EventSourceDispatch (s=0x1a695f0, callback=<value optimized out>, user_data=<value optimized out>) at kernel/qguieventdispatcher_glib.cpp:146 #25 0x00007fbdd853f2d1 in g_main_dispatch (context=0x1a68520) at gmain.c:1960 #26 IA__g_main_context_dispatch (context=0x1a68520) at gmain.c:2513 #27 0x00007fbdd8543128 in g_main_context_iterate (context=0x1a68520, block=<value optimized out>, dispatch=<value optimized out>, self=<value optimized out>) at gmain.c:2591 #28 0x00007fbdd85432dc in IA__g_main_context_iteration (context=0x1a68520, may_block=1) at gmain.c:2654 #29 0x00007fbddf8da673 in QEventDispatcherGlib::processEvents (this=0x1a5c770, flags=<value optimized out>) at kernel/qeventdispatcher_glib.cpp:412 #30 0x00007fbddeaa603e in QGuiEventDispatcherGlib::processEvents (this=0x0, flags=<value optimized out>) at kernel/qguieventdispatcher_glib.cpp:204 #31 0x00007fbddf8afaa2 in QEventLoop::processEvents (this=<value optimized out>, flags=) at kernel/qeventloop.cpp:149 #32 0x00007fbddf8afe74 in QEventLoop::exec (this=0x7fffc0628d30, flags=) at kernel/qeventloop.cpp:201 #33 0x00007fbddf8b4aeb in QCoreApplication::exec () at kernel/qcoreapplication.cpp:1003 #34 0x000000000040974d in main (argc=<value optimized out>, argv=<value optimized out>) at /usr/src/debug/kde-base/akregator-4.4.5/akregator-4.4.5/akregator/src/main.cpp:103 Reported using DrKonqi

Created attachment 52810 [details] New crash information added by DrKonqi akregator (1.6.5) on KDE Platform 4.5.2 (KDE 4.5.2) using Qt 4.6.3 Yo, guess what. Power went out, feedlist.opml got currupt *again* just because Akregator keeps the darn file open even when it's been weeks since I changed my feeds (also nor me nor my HDD is happy for all those unnecesarry writes you're making). Not that I expect you to care. Just wanted to inform you that the next time this happens I'm ditching your shitware. Just like the local Debian/Ubuntu developer I happen know so really no one likes your shit. Cheers!

Created attachment 55956 [details] New crash information added by DrKonqi akregator (1.6.5) on KDE Platform 4.5.5 (KDE 4.5.5) using Qt 4.7.0 - What I was doing when the application crashed:I removed contents the feeds.opml file and then try to add a feed in Akregator. Few days ago I've had some troubles with my file system. After repair it via fsck contents from plasma desktop configuration file appeared in feeds.opml, so I removed them. -- Backtrace (Reduced): #7 0x0335f497 in Akregator::FeedList::allFeedsFolder() () from /usr/lib/kde4/akregatorpart.so #8 0x033c6855 in Akregator::MainWidget::qt_metacall(QMetaObject::Call, int, void**) () from /usr/lib/kde4/akregatorpart.so [...] [...] #11 0x01035f99 in QAction::triggered (this=0x82d49a8, _t1=false) at .moc/release-shared/moc_qaction.cpp:263 #12 0x010378dc in QAction::activate (this=0x82d49a8, event=QAction::Trigger) at kernel/qaction.cpp:1256 #13 0x01039b68 in QAction::event (this=0x0, e=0x0) at kernel/qaction.cpp:1182
