New commits: commit 2e486daff35ab16e810bfdafb24b19bcbf2fe8cd Author: Michael Stahl <mst...@redhat.com> Date: Fri Jul 21 12:01:01 2017 +0200 tdf#108867 sw: fix dangling text box frame format pointers in Undo If the text box is removed, the SwFrameFormat of the drawing shape still retains a pointer to the frame SwFrameFormat, and the latter is owned by the SwUndoFlyBase. This is pretty bad, so try to clear & reset the connection between them in SwUndoFlyBase::InsFly() and DelFly(). Hopefully nothing will actually delete the drawing shape SwFrameFormat while the Undo object is alive. Note that when the SwUndoInsLayFormat is created when the text box is added, the GetOtherTextBoxFormat() returns null as it's set later, that's why the constructor can't do anything.
