What is the bug or the crash?

Exporting any elevation profile to PDF there is a scaling problem in the created PDF. Only a very small part of the upper left corner of the profile is visible in the exported PDF. Export the profile as image is correct using the same chart ranges as in PDF export.
I suppose it is a scaling problem.

Steps to reproduce the issue

  1. Open an elevation raster/DEM
  2. Open the elevation profile panel
  3. Capture a line on the DEM
  4. Click on Export PDF tool
  5. Accept default chart ranges ans save
  6. Open the exported PDF to see the issue.
