bug #200796 states the same backtrace and was supposed to be fixed for KDE 4.4.4. However, this doesn't seem to be the case. So this is still valid... [Comment from a bug triager] From bug 262653 (KDE SC 4.5.4): - What I was doing when the application crashed: I wanted to check a long config file, tried to scroll down and Kate crashed. Why is there still no auto-backup feature for unsaved documents? I lost data multiple times :( From bug 266427 (KDevelop on KDE SC 4.5.5): - What I was doing when the application crashed: Scrolled document quickly till the end (approx) using mouse. - Updated backtrace (4.5.5): [KCrash Handler] #7 0x018b3d36 in KateLineLayout::viewLineCount (this=0x0) at /usr/src/debug/kdelibs-4.5.5/kate/render/katelinelayout.cpp:173 #8 0x018b0fd5 in KateLayoutCache::lastViewLine (this=0x9a56a30, realLine=1425) at /usr/src/debug/kdelibs-4.5.5/kate/render/katelayoutcache.cpp:448 #9 0x018b1029 in KateLayoutCache::viewLineCount (this=0x9a56a30, realLine=1425) at /usr/src/debug/kdelibs-4.5.5/kate/render/katelayoutcache.cpp:453 #10 0x018b148b in KateLayoutCache::displayViewLine (this=0x9a56a30, virtualCursor=..., limitToVisible=false) at /usr/src/debug/kdelibs-4.5.5/kate/render/katelayoutcache.cpp:416 #11 0x01919d1d in KateViewInternal::scrollPos (this=0x99de348, c=..., force=false, calledExternally=false) at /usr/src/debug/kdelibs-4.5.5/kate/view/kateviewinternal.cpp:491 #12 0x0191a4e1 in KateViewInternal::scrollLines (this=0x99de348, line=1470) at /usr/src/debug/kdelibs-4.5.5/kate/view/kateviewinternal.cpp:377 #13 0x01922957 in KateViewInternal::qt_metacall (this=0x99de348, _c=QMetaObject::InvokeMetaMethod, _id=<value optimized out>, _a=0xbf8cc9e8) at /usr/src/debug/kdelibs-4.5.5/i686-redhat-linux-gnu/kate/kateviewinternal.moc:125 #14 0x04639bcb in QMetaObject::metacall (object=0x99de348, cl=QMetaObject::InvokeMetaMethod, idx=35, argv=0xbf8cc9e8) at kernel/qmetaobject.cpp:237 #15 0x04648a75 in QMetaObject::activate (sender=0x99d8730, m=0x7759c94, local_signal_index=2, argv=0xbf8cc9e8) at kernel/qobject.cpp:3295 #16 0x075229c4 in QAbstractSlider::sliderMoved (this=0x99d8730, _t1=1470) at .moc/release-shared/moc_qabstractslider.cpp:195 #17 0x07236868 in QAbstractSlider::setSliderPosition (this=0x99d8730, position=<value optimized out>) at widgets/qabstractslider.cpp:494 #18 0x072d3f2b in QScrollBar::mouseMoveEvent (this=0x99d8730, e=0xbf8cd1a0) at widgets/qscrollbar.cpp:673 #19 0x019283aa in KateScrollBar::mouseMoveEvent (this=0x99d8730, e=0xbf8cd1a0) at /usr/src/debug/kdelibs-4.5.5/kate/view/kateviewhelpers.cpp:111 ... *** Bug 262653 has been marked as a duplicate of this bug. *** *** Bug 266427 has been marked as a duplicate of this bug. *** Created attachment 58045 [details]
