exported SVG profile file crashes Inkscape

[HLHJ]

Ristretto Image Viewer does open SVGs correctly. This may therefore be an Inkscape bug. Apologies if this is the case.

Steps to replicate:

• Download, say, this ETOPO1 data.
• Install the "Profile tool".
• Make a cross-section using "Profile tool".
• Tick the "Show cursor" box in the "Profile tool" pane.
• Save cross-section profile as an SVG file using the "Save as" button.
• Outside QGIS, attempt to open the SVG file with Inkscape.
• Inkscape will crash without opening the file. Pop-up message: "Inkscape encountered an internal error and will close now", with a "Close" button.
• Back in QGIS, untick the "Show cursor" box and save an SVG file again.
• The new file will open (the canvas size is way off, but that's minor).

Desired behaviour:
If this is not a problem with Inkscape, either the export function should not care whether the cursor is on, or it should display a warning that the file will not export properly if the cursor is shown.

Thank you for the really useful tool.
