OMPL segfault during IRM AY2425

[adverley]

At least on three different student laptops, there was a problem when running planner.plan_to_tcp_pose() that caused the jupyter notebook kernel to crash. When looking at system logs, there is a segfault going on. Given the time constraint during the practicals, I could not debug in depth but it is probably OMPL related since it did not crash when the IK solver gave no feasible solutions (and hence the procedure returns without running OMPL). I can't reproduce it since I don't have access to their laptop but we should look at reproducing this issue for future installs.
