Document with image to test contour editor

Open attached document. Right-click image. Choose "Edit contour" from submenu "Wrap".

In the contour editor select the rectangle tool and draw a rectangle over the image.
Expected behavior: The "Apply" button top-left is enabled.
Seen behavior: Crash.

The crash happens wether OpenGL is enabled or not.

On pc Debian x86-64 with master sources updated today, I could reproduce this.

It's due to an infinite recursion with this pattern:

Comment 4 Armin Le Grand 2018-12-05 08:43:24 UTC
Looks like a endless loop - 1st entry same as last one. Need to debug - there is no reason that SdrObject::InsertedStateChange() triggers ContourWindow::SdrObjCreated all the time - and that tries to convert to SdrPathObj (why at all?) in SdrEditView::ConvertMarkedToPathObj...
