There is no problem without Images.jl.

I can confirm this error. However, I do not understand the error message or why such an error is thrown out. Maybe we should open an issue in the Julia repo or Images.jl repo to see if anyone would know what is the issue here.
Hi. I'm having the same problem. Any news about it? Were you able to solve it?
What version of Julia are you using? What is you Pkg.status()? I noticed this as well and it might be related to JuliaLang/julia#18465
