--- Comment #3 from Wood <w0...@mail.com> --- (In reply to Friedrich W. H. Kossebau from comment #1) > Thanks for the report. Never seen before. Can you remember what you exactly > did? What language do you develop with? Did you enable/disable plugins? > > Developer notes: > Backtrace possibly hints to a QAction accessed which no longer exists. The > QAction pointed to by ActionsQuickOpenItem is added during a filtering run, > where ActionsQuickOpenProvider::setFilterText() queries > KActionCollection::allCollections() for all actions. But there is no > mechanism to catch actions being deleted at a later point, while the item is > still existing. > > The rest of the backtrace hints that the popup of the QuickOpen menu is > triggered, and possibly at that point it still holds the results of the last > search. > > Needs more investigation. just in case it helps, I poked around a little bit in gdb at the disassembled code and indeed ActionsQuickOpenItem::m_action value looks like a horked pointer: 0x4000000000000090 Dump of assembler code for function _ZNK7QAction4iconEv: 0x00007f2d92c46510 <+0>: push rbx 0x00007f2d92c46511 <+1>: mov rsi,QWORD PTR [rsi+0x8] 0x00007f2d92c46515 <+5>: mov rbx,rdi 0x00007f2d92c46518 <+8>: add rsi,0x90 0x00007f2d92c4651f <+15>: call 0x7f2d92c3c780 <QIcon::QIcon(QIcon const&)@plt> => 0x00007f2d92c46524 <+20>: mov rax,rbx (gdb) info registers rax 0x1 1 rbx 0x7ffe08c73b00 140729045695232 rcx 0xca89030 212373552 rdx 0x188607a0 411436960 rsi 0x4000000000000090 4611686018427388048 rdi 0x7ffe08c73b00 140729045695232 rbp 0x7ffe08c73b70 0x7ffe08c73b70 rsp 0x7ffe08c73b00 0x7ffe08c73b00 r8 0x7f01fec0 2130837184 r9 0x83 131 r10 0xffffffff 4294967295 r11 0x0 0 r12 0x171e9fd0 387882960 r13 0x7ffe08c73bd0 140729045695440 r14 0x2a529d0 44378576 r15 0x1 1 rip 0x7f2d734b3e69 0x7f2d734b3e69 <ActionsQuickOpenItem::icon() const+41> eflags 0x206 [ PF IF ] cs 0x33 51 ss 0x2b 43 ds 0x0 0 es 0x0 0 fs 0x0 0 gs 0x0 0 -- You are receiving this mail because: You are watching all bug changes.
