Webots crashes when adding Shape to Track.boundingObject via GUI (R2023b)

[kik1hu]

When I click "Add → Shape" under the boundingObject field of a **Track** node in the Webots scene tree, Webots crashes instantly, even before I have a chance to set the geometry.

This does not happen under other node types like Solid or Robot.

Steps to Reproduce

1. Create a Track node in a .wbt world.
2. Expand Track → boundingObject in the scene tree.
3. Right-click and choose "Add → Shape".
4. Webots crashes immediately.

Segmentation fault occurs instantly after clicking "Add → Shape":
/usr/local/bin/webots: line 105: 6095 Segmentation fault (core dumped) "$webots_home/bin/webots-bin" "$@"

• The crash is immediate, and happens before any geometry is set.
• The issue seems specific to Track.boundingObject.
• Workaround: manually write the Shape node in the .wbt file to avoid GUI triggering the bug.

I wasn't able to reproduce this on R2023b or R2025a on Windows or Ubuntu. Is there a specific world the crash occurs in or is it just any Track instance? Also, is the bug still present in R2025a?
