Bug ID: 141887
Summary: Crash on closing Writer via window decoration (X) with
unmodified document and active IM
Product: LibreOffice
Version: 7.2.0.0.alpha0+ Master
Hardware: All
OS: Linux (All)
Status: UNCONFIRMED
Severity: normal
Priority: medium
Component: Writer
Assignee: [email protected]
Reporter: [email protected]
Description:
Happens with kf5 and gtk3, but not gen. For whatever reason, gen doesn't
trigger the following codepath / bt:
#0 SwEditWin::Command (this=0x555559f5cd10, rCEvt=...)
at sw/source/uibase/docvw/edtwin.cxx:5360
#1 ImplCallCommand (pChild=..., nEvt=nEvt@entry=<incomplete type>,
pData=pData@entry=0x7fffffff0400, bMouse=bMouse@entry=false,
pPos=pPos@entry=0x0)
#2 ImplHandleExtTextInput (nCursorFlags=<optimized out>, nCursorPos=<optimized
out>, pTextAttr=0x0, rText=..., pWindow=0x555556b992f0)
#3 ImplWindowFrameProc (_pWindow=0x555556b992f0, nEvent=<optimized out>,
pEvent=<optimized out>)
#4 SalFrame::CallCallback (pEvent=0x7fffffff07e0,
nEvent=SalEvent::ExtTextInput, this=<optimized out>)
#5 GtkSalFrame::CallCallbackExc (this=<optimized out>,
nEvent=nEvent@entry=SalEvent::ExtTextInput, pEvent=pEvent@entry=0x7fffffff07e0)
#6 GtkSalFrame::IMHandler::sendEmptyCommit (this=this@entry=0x55555c77f3c0)
#7 GtkSalFrame::IMHandler::endExtTextInput (this=0x55555c77f3c0)
#8 vcl::Window::dispose (this=this@entry=0x555559f5cd10)
at vcl/source/window/window.cxx:403
#9 SwEditWin::dispose (this=0x555559f5cd10)
At this point m_rView.GetWrtShellPtr() is already gone, but SwEditWin::Command
relies on m_rView.GetWrtShell().
FWIW:
- Writer: with crash fix applied, just closes and no undo entry, so no crash on
Ctrl+Z while in pre-selection.
- Calc: closes IM and takes the current pre-selection => modified doc, so get
close modified dialog. Crash on undo.
- Impress: same as Calc.
- Draw: same as Impress, if you open a doc with a shape and start modifying its
text.
- Math: just closes. Creates undo object and crashes on Ctrl+Z while in
pre-selection.
Steps to Reproduce:
1. Start LO Writer
2. Activate some IM and type a character, to be in IM pre-selection
3. Close Writer via window decoration (X)
Actual Results:
crash
Expected Results:
no crash
Reproducible: Always
User Profile Reset: No
