            Bug ID: 141888
           Summary: Crash on undo while in IM pre-selection in Calc,
                    Impress and Math
           Product: LibreOffice
           Version: 7.2.0.0.alpha0+ Master
          Hardware: All
                OS: All
            Status: UNCONFIRMED
          Severity: normal
          Priority: medium
         Component: LibreOffice
          Assignee: libreoffice-bugs at lists.freedesktop.org
          Reporter: glogow at fbihome.de

Found while fixing bug 141887 (Writer IM crash).

STR:

1. Start LO Calc, Impress, Draw or Math (not Writer! Didn't test Base)
2. Activate some IM and type a character, to be in IM pre-selection
3. Undo via shortcut (Ctrl+Z)

Expected result:
no crash

Actual result:
crash

soffice.bin: svl/source/undo/undo.cxx:679: bool
SfxUndoManager::ImplUndo(SfxUndoContext*): Assertion `!"SfxUndoManager::Undo:
not possible when within a list action!"' failed.

-----

All these modules create an undo entry while still in pre-selection (you can
see the enabled undo toolbar button). Writer doesn't do that, so no crash
happens. IMHO the other applications shouldn't create the Undo entry based on
the pre-selection data, which would prevent the crash.
