Description
This bug was reported in rviz originally: https://github.com/ros-visualization/rviz/issues/1541.
I suspect that the function transformLaserScanToPointCloud() doesn't correctly handle the single ray scan?

Research direction
Start by tracing transformLaserScanToPointCloud() and reproduce the case with a LaserScan containing a single ray, using the linked rviz issue for context. Done means the resulting point cloud is produced correctly and the single-ray scan displays in rviz.
