The default radiation linear wave test gives the following header:
# gid i x1v j x2v k x3v dens velx vely velz eint

while the problem is 1D and therefore the data line looks like:
00000 0002 7.81250e-03 9.99999e-01 -4.03501e-07 4.16136e-18 -7.82042e-18 3.74653e-01

This would prevent the default plot_tab.py to load the data correctly unless the header is corrected. It's a small issue. Just leave a record here for a notice.
