Error in magic function detect_rdata about fileio.jl

[ericphanson]

ran into this today too and Simon pointed me to a corrupt file as well. I think this is actually a FileIO bug though, because it should just overwrite the file, not give a confusing error.

Maybe there is a corrupted file at that path?

Thank you - I think that was the problem.

Right, FileIO can provide a fallback for broken files.

In the meantime, this is also a Makie issue in https://github.com/JuliaPlots/Makie.jl/blob/beb3fcd1e460b3207b933dcfa758d6df7d48db3d/src/display.jl#L218-L222

Either use FileIO.query(filename; checkfile=false) or remove the string version method could probably fix this one.

shell> touch test.png

julia> query("test.png")
