Julia crashes on Interrupt when using PythonCall

**Affects:** PythonCall

**Describe the bug**
I just turned off threads to make PythonCall work, but now I experience that every time I try interrupting the julia REPL (with PythonCall loaded and used inside a WebServer) it results in a fatal error which crashes the whole Julia REPL (however I would like to stay in the julia REPL)

Here the error message
```julia
^Cfatal: error thrown and no exception handler available.

I was not able to simplify it to a MWE yet. Maybe the above error is already somehow self-explaining.
