Version: (using Devel) Installed from: Compiled sources To reproduce: Create a new event (I had an event spanning multiple days). Put it on e.g. Monday, and confirm. In agenda view, the event is displayed. Now, edit the event, edit the recurrences, and say it recurs every 2 days. Click apply, and KOrganizer crashes.

I've just tried to reproduce. It doesn't crash but I've see a strange behaviour: if the event is on multiple days, only the first is show on the week view.
I see the same behavior also in other views. But the backtrace differs. What I did: Open a recurring event, click on Edit... next to the recurrence indicator and then change from recurs every 13 days to recurs every 14 days. Click OK, and click OK again. Sometimes this works, sometimes it crashes. Actually, most of the time it crashes. I think there is a dangling Incidence pointer around. The edit dialog deleted an incidence object IMHO, and then the next component accessing the incidence triggers the crash. If there is valid memory by hazard, nothing happens, otherwise the crash occurs. Probably the view was about to get notified about the changed/deleted incidence in changeIncidenceDisplay(), but accessed the old pointer again, which is not wrong IMHO. The backtrace I get when doing this when being in the month view: Application: KOrganizer (korganizer), signal SIGSEGV [Thread debugging using libthread_db enabled] [New Thread 0xb504a720 (LWP 26252)] [KCrash handler] #6 0xb56804c7 in free () from /lib/tls/i686/cmov/libc.so.6 #7 0xb7dd9a3d in qFree () from /usr/lib/libQtCore.so.4 #8 0xb7e21ec0 in QString::free () from /usr/lib/libQtCore.so.4 #9 0xb765021d in ~QString (this=0xbfd42d6c) at /usr/include/qt4/QtCore/qstring.h:831 #10 0xb764ef75 in KOEventViewer::changeIncidenceDisplay (this=0x816ea60, incidence=0x839a658, action=1) at /home/tom/_coding/kde/src/kdepim/korganizer/koeventviewer.cpp:135 #11 0xb7823514 in CalendarView::changeIncidenceDisplay (this=0x8111ae0, incidence=0x839a658, action=1) at /home/tom/_coding/kde/src/kdepim/korganizer/calendarview.cpp:763 #12 0xb78259e2 in CalendarView::incidenceChanged (this=0x8111ae0, oldIncidence=0x8381740, newIncidence=0x839a658, what=9) at /home/tom/_coding/kde/src/kdepim/korganizer/calendarview.cpp:703 #13 0xb7825a3b in CalendarView::incidenceChanged (this=0x8111ae0, oldIncidence=0x8381740, newIncidence=0x839a658) at /home/tom/_coding/kde/src/kdepim/korganizer/calendarview.cpp:644 #14 0xb782835f in CalendarView::qt_metacall (this=0x8111ae0, _c=QMetaObject::InvokeMetaMethod, _id=91, _a=0xbfd42fc8) at /home/tom/_coding/kde/build/kdepim/korganizer/calendarview.moc:478 #15 0xb7edf4f9 in QMetaObject::activate () from /usr/lib/libQtCore.so.4 #16 0xb7edfbc2 in QMetaObject::activate () from /usr/lib/libQtCore.so.4 #17 0xb64571cb in KOrg::IncidenceChangerBase::incidenceChanged ( this=0x81ca410, _t1=0x8381740, _t2=0x839a658) at /home/tom/_coding/kde/build/kdepim/korganizer/interfaces/korganizer/incidencechangerbase.moc:106 #18 0xb78bc1a1 in IncidenceChanger::changeIncidence (this=0x81ca410, newinc=0x839a658, oldinc=0x8381740, action=-1, counter=false) at /home/tom/_coding/kde/src/kdepim/korganizer/incidencechanger.cpp:303 #19 0xb783e075 in KOEventEditor::processInput (this=0x8356ce0) at /home/tom/_coding/kde/src/kdepim/korganizer/koeventeditor.cpp:302 #20 0xb783964a in KOIncidenceEditor::slotApply (this=0x8356ce0) at /home/tom/_coding/kde/src/kdepim/korganizer/koincidenceeditor.cpp:109 #21 0xb783b4eb in KOIncidenceEditor::qt_metacall (this=0x8356ce0, _c=QMetaObject::InvokeMetaMethod, _id=16, _a=0xbfd43228) at /home/tom/_coding/kde/build/kdepim/korganizer/koincidenceeditor.moc:125 #22 0xb783e5b6 in KOEventEditor::qt_metacall (this=0x8356ce0, _c=QMetaObject::InvokeMetaMethod, _id=89, _a=0xbfd43228) at /home/tom/_coding/kde/build/kdepim/korganizer/koeventeditor.moc:69 #23 0xb7edf4f9 in QMetaObject::activate () from /usr/lib/libQtCore.so.4 #24 0xb7edfbc2 in QMetaObject::activate () from /usr/lib/libQtCore.so.4 #25 0xb6712e97 in KDialog::applyClicked (this=0x8356ce0) at /home/tom/_data/kde/build/kdelibs/kdeui/kdialog.moc:235 #26 0xb6715fba in KDialog::slotButtonClicked (this=0x8356ce0, button=8) at /home/tom/_data/kde/src/kdelibs/kdeui/dialogs/kdialog.cpp:903 #27 0xb6716518 in KDialog::qt_metacall (this=0x8356ce0, _c=QMetaObject::InvokeMetaMethod, _id=33, _a=0xbfd4343c) at /home/tom/_data/kde/build/kdelibs/kdeui/kdialog.moc:181 #28 0xb67e968a in KPageDialog::qt_metacall (this=0x8356ce0, _c=QMetaObject::InvokeMetaMethod, _id=68, _a=0xbfd4343c) at /home/tom/_data/kde/build/kdelibs/kdeui/kpagedialog.moc:63 #29 0xb783b21c in KOIncidenceEditor::qt_metacall (this=0x8356ce0, _c=QMetaObject::InvokeMetaMethod, _id=68, _a=0xbfd4343c) at /home/tom/_coding/kde/build/kdepim/korganizer/koincidenceeditor.moc:104 #30 0xb783e5b6 in KOEventEditor::qt_metacall (this=0x8356ce0, _c=QMetaObject::InvokeMetaMethod, _id=68, _a=0xbfd4343c) at /home/tom/_coding/kde/build/kdepim/korganizer/koeventeditor.moc:69 #31 0xb7edf4f9 in QMetaObject::activate () from /usr/lib/libQtCore.so.4 #32 0xb7edfbc2 in QMetaObject::activate () from /usr/lib/libQtCore.so.4 #33 0xb7ee37c3 in QSignalMapper::mapped () from /usr/lib/libQtCore.so.4 #34 0xb7ee3fcd in QSignalMapper::map () from /usr/lib/libQtCore.so.4 #35 0xb7ee41be in QSignalMapper::map () from /usr/lib/libQtCore.so.4 #36 0xb7ee42d7 in QSignalMapper::qt_metacall () from /usr/lib/libQtCore.so.4 #37 0xb7edf4f9 in QMetaObject::activate () from /usr/lib/libQtCore.so.4 #38 0xb7edf930 in QMetaObject::activate () from /usr/lib/libQtCore.so.4 #39 0xb5faeeb1 in QAbstractButton::clicked () from /usr/lib/libQtGui.so.4 #40 0xb5d0ef49 in ??

I believe this is fixed now. Please double-check and close if it no longer crashes the bug was due to the incidenceChanger argument order mixup
Yes, now it works fine. Apparently was because of the changeIncidence() parameter mixup.
