ros2 segmentation fault while importing layout

[Howard-Ryu-Brooklyn]

Thanks for contributing to PlotJuggler. You are great!

Problem description

Whenever I try to import layout, Error prints shown as below.

I tried this both in GUI and in CLI on the start with -l command
I'm using ubuntu 22.04 ros2 humble.

FYI, it never happened when I install plotjuggler through snap. but that has a problem with subscribing custom package message.

Thank you, in advanced.

I am experiencing the same thing, but it seems to have to do with split panels. I am only able to import layout files if it is a single panel per tab.

Hi @Howard-Ryu-Brooklyn,

Do you use WSL2 ?

Because I have the same issue when using Ubuntu 22.04 in WSL2.
What worked for me was also to uninstall the Debian packages and to re-install using the snap image.
I was about to open an issue, but that would just be a duplicate.

Here the steps to reproduce the error:

Plateform:

• Ubuntu 22.04 (WSL2)
• Kernel Linux 5.15.90.1-microsoft-standard-WSL2
• Humble ROS2 distribution
• Plotjuggler and ros plugin installed from Debian packages

Steps:

1. Launch plotjuggler and subscribe to a topic;
2. Plot some data (I tried with a simple Float64 topic) and modify the layout (I just split the window);
3. Export the layout to .xml;
4. Load the layout.
   After being prompted to subscribe to the topic, whether the answer is yes or no, the application crashes.

Bash output at crash time:

I am experiencing the same error on WSL2 5.15.90.1-microsoft-standard-WSL2 and on native Ubuntu 22.04 with the debian packages installed as sudo apt install ros-humble-plotjuggler ros-humble-plotjuggler-ros .
As long as I don't load a split view layout, it doesn't crash. As soon as I load a split layout, the same error as described by @tpoignonec occurs.
As mentioned above, with the snap install there are no issues whatsoever. I hope this helps finding the issue.
