--- Comment #1 from Szőts Ákos <szots...@gmail.com> --- Created attachment 143782 --> https://bugs.kde.org/attachment.cgi?id=143782&action=edit New crash information added by DrKonqi kontact (5.18.3 (21.08.3)) using Qt 5.15.2 - What I was doing when the application crashed: I created a new task (with recurrency). When I clicked OK, KOrganizer crashed. The event had been created successfully before, though. -- Backtrace (Reduced): #6 QSortFilterProxyModelPrivate::proxy_to_source (this=0x56554185b0d0, proxy_index=...) at itemmodels/qsortfilterproxymodel.cpp:571 #7 0x00007f7138b6b2c9 in QSortFilterProxyModel::mapToSource (proxyIndex=..., this=0x5655419cc2c0) at itemmodels/qsortfilterproxymodel.cpp:3171 #8 QSortFilterProxyModelPrivate::store_persistent_indexes (this=<optimized out>) at itemmodels/qsortfilterproxymodel.cpp:1248 #9 0x00007f7138b6cd5b in QSortFilterProxyModelPrivate::_q_sourceLayoutAboutToBeChanged (this=0x56554185b0d0, sourceParents=..., hint=<optimized out>) at itemmodels/qsortfilterproxymodel.cpp:1639 #10 0x00007f7138bd5078 in doActivate<false> (sender=0x5655419cb430, signal_index=9, argv=0x7fff36d06a30) at kernel/qobject.cpp:3898 -- You are receiving this mail because: You are watching all bug changes.
