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