Reproduce by: 1) In a new document, insert a 5x5 tabular.
2) Fill the first row (place the cursor in first cell and type a TAB b TAB c TAB d TAB e). 3) Now, select this row and copy it (Control-C). 4) Place the cursor on the third row and paste (Control-V) repeatedly. Here is the backtrace: (gdb) where #0 0xef4f4a70 in kill () #1 0xef4ba6e4 in abort () #2 0x219548 in lyx::abort () at abort.C:9 #3 0x9798c in error_handler (err_sig=11) at ../src/lyx_main.C:229 #4 <signal handler called> #5 Row::par (this=0xb) at lyxrow.h:90 #6 0xfa358 in LyXText::init (this=0x527c50, bview=0x4f87d8, reinit=false) at text2.C:93 #7 0xfdbc4 in LyXText::fullRebreak (this=0x527c50, bview=0x4f87d8) at text2.C:940 #8 0x17c8bc in InsetText::updateLocal (this=0x520b94, bv=0x4f87d8, what=1, mark_dirty=false) at insettext.C:624 #9 0x17cc4c in InsetText::edit (this=0x520b94, bv=0x4f87d8, x=0, y=0, button=0) at insettext.C:676 #10 0x1765cc in InsetTabular::activateCellInset (this=0x5169e0, bv=0x4f87d8, x=0, y=0, button=0, behind=false) at insettabular.C:1928 #11 0x1720fc in InsetTabular::localDispatch (this=0x5169e0, bv=0x4f87d8, action=LFUN_MENUWRITE, arg=@0xefffeff8) at insettabular.C:1110 #12 0xa7154 in LyXFunc::dispatch (this=0x4d8490, ac=4, do_not_use_this_arg=@0xeffff088) at lyxfunc.C:871 #13 0xa4848 in LyXFunc::processKeySym (this=0x4d8490, keysym=115, state=4) at lyxfunc.C:353 #14 0x1c070 in BufferView::Pimpl::workAreaKeyPress (this=0x500c90, keysym=115, state=4) at BufferView_pimpl.C:513 #15 0x249060 in SigC::ObjectSlot2_<void, unsigned long, unsigned int, BufferView::Pimpl>::callback (d=0x501c7c, p1=115, p2=4) at ../sigc++/object_slot.h:250 #16 0x26f2bc in SigC::Callback2<void, unsigned long, unsigned int>::call ( this=0x501c7c, p1=@0xeffff37c, p2=@0xeffff380) at ../sigc++/slot.h:456 #17 0x26f3e0 in SigC::Signal2<void, unsigned long, unsigned int, SigC::Marshal<void> >::emit (this=0x500cc4, p1=@0xeffff37c, p2=@0xeffff380) at ../sigc++/basic_signal.h:472 #18 0x26f708 in SigC::Signal2<void, unsigned long, unsigned int, SigC::Marshal<void> >::operator() (this=0x500cc4, p1=@0xeffff37c, p2=@0xeffff380) at ../sigc++/basic_signal.h:450 #19 0x54744 in WorkArea::work_area_handler (ob=0x501668, event=9, key=19, xev=0xef766e3c) at WorkArea.C:541 #20 0x528b0 in C_WorkArea_work_area_handler (ob=0x501668, event=9, key=19, xev=0xef766e3c) at WorkArea.C:65 #21 0xef70a658 in fl_handle_it () #22 0xef70a74c in fl_handle_object () #23 0xef6f7934 in fl_handle_form () #24 0xef6f7d80 in do_keyboard () #25 0xef6f8654 in do_interaction_step () #26 0xef6f8f84 in fl_treat_interaction_events () #27 0xef6f8fd4 in fl_check_forms () #28 0x1948b0 in GUIRunTime::runTime () at GUIRunTime.C:86 #29 0x957a8 in LyXGUI::runTime (this=0x4c5328) at lyx_gui.C:316 #30 0x974d0 in LyX::LyX (this=0xeffffa28, argc=0xeffffaa4, argv=0xeffffac4) at ../src/lyx_main.C:177 #31 0xc3f54 in main (argc=2, argv=0xeffffac4) at ../src/main.C:38 -- Kayvan A.
