Loading layout file with spit panel always causes segmentation fault

[scrice]

First of all, love this tool. I'm excited to use it.

I have noticed that if I try to load even the most basic of layout files with a horizontal or vertical split of any kind, plotjuggler crashes. This is when running the ros2 package. This is a pretty critical issue as it means I have to manually recreate layouts every time I run plotjuggler if I want anything more than a single plot panel (tabs do still seem to work though).

Running the command:
ros2 run plotjuggler plotjuggler --layout test_layout.xml

The same behavior happens when loading the test layout file through the gui.

I am running ros2 humble on ubuntu 22.04 on wsl.

I experience the same behavior. Similar setup, but not using WSL.

Same issue, with PlotJuggler running in a minimal ubuntu 22.04 docker.

Having the same issue here, seems to only crash on splits for me as well.
Running Ubuntu 22.04, Ros2 Humble, plotjuggler version (3.7.1-1jammy.20230919.230903)
