Old config file causes crash in Iron

[dcconner]

From https://answers.ros.org/question/417874/rviz2-crashing-in-iron/

My old file from Humble caused crash when I switched to Iron. Deleting the file allowed me to load RViz.

I suggest trying to catch any issues on configuration load and provide suitable error message to user.

Unfortunately, I don't have time to work on this so I suspect this is a future enhancement.

I have the same problem, and narrowed it down to rviz_default_plugins/Camera in the rviz file causing the segmentation fault. Even if I remove this, add the camera plugin again, save and reopen causes the same crash.

Similar issue here - but I found this thread when searching for bugs with the Camera plugin in iron/rviz2. When I start a new rviz instance and add a Camera plugin it's initially fine until I select the topic (/image_raw). As soon as I select this topic rviz crashes.

Exact same setup works when starting rviz2 from a terminal with Humble sourced instead of Iron, & the camera image can be visualised just fine.

This is a different bug, and one I can reproduce locally on Iron, though not on Rolling. @ahcorde since you've been doing work in this area, can you maybe take a look?

In any case, please open up a separate issue for that.
