Inkscape crashes (SEGV) editing a path with pattern fill

My recipe for a crash:

Create document 1000px × 1000px.
[Ctrl]+[Shift]+[F] Fill and stroke toolbox
[Ctrl]+[Shift]+[A] Alignment toolbox
[Ctrl]+[I] load image - 810px × 540px.
Align to centre of page.
[F1] Select image
[Alt]+[I] Object to pattern
[Del] Delete object
[F4] Create rectangle
Set dimensions to be 810px × 540px in toolbar.
Align to centre of page.
[F1] Select rectangle.
[Ctrl]+[Shift]+[C] Convert to path
Set fill to be pattern.
[F2] Node selection.
Click pointer on left edge of path to select both top left and bottom left nodes.
Drag rightwards.
Path bends.
Inkscape crashes.

Core dump available on request.

I have attached an SVG file with the pattern in the path, prior to trying to edit the path.
