I have a package that uses PythonCall.jl to import and use the python library TTS. Importing Plots.jl seems to be causing a segmentation fault. Below is a minimum working example. If I `import Pytest` and then call `f()`, it causes a segmentation fault.

If I just `include(Pytest.jl)` from a julia session, do `using .Pytest` and call `f()`, I still get a segmentation fault when Plots.jl is imported.

I can switch to another plotting package for now, but wanted to post here in case people think this is important or in case anyone thinks I’m doing silly things I shouldn’t be doing.

Complete package (the contents of Pytest.jl):

```julia
module Pytest

ENV["COQUI_STUDIO_TOKEN"] = "TOKEN_HERE" # need this to initially download files for TTS
conda_environment_directory = joinpath(@ __DIR__ , "..", ".CondaPkg", "env")
ENV["JULIA_CONDAPKG_ENV"] = conda_environment_directory
ENV["JULIA_PYTHONCALL_EXE"] = joinpath(conda_environment_directory, "bin", "python")

using PythonCall
# using Plots # causing segfault?

const p = Ref{Py}()
function __init__ ()
    p[] = pyimport("TTS.api").TTS

    return nothing
end

f() = p[]("tts_models/en/jenny/jenny")

export f

end

```

Update: `import CairoMakie` instead of `import Plots` also causes the same error. Any ideas?

Tagging @cjdoris to see if they have any insights.
