QGIS 3.4.4 crash when using dynamic image in html textfield in print layout

[qgib]

Author Name: Dennis Real (Dennis Real)
Original Redmine Issue: 21178
Affected QGIS version: 3.6.0
Redmine category:map_composer/printing

---

Steps to reproduce:

Note: Steps 1-8 already done in attached file. Unzip in /tmp to get right path to images.

1. Create new qgis project with some layers (OSM Standard as background, 1 KML with some points, 1 .ods table with additional information)
2. Connect KML (waypoint name) with table (column "ID")
3. Create new print layout
4. Create atlas over kml waypoints
5. insert text field with html source
6. include dynamic image in html using atlas feature id:

7. Click through atlas. Image will change as expected 8. Save project and close qgis 9. Start qgis and open project again 10. Open print layout -> CRASH!

Reproducability: Always.
