Segfault scanning package that depends on CondaPkg / PythonCall

[ssfrr]

VSCode was failing to scan for symbols, and always failing on the same package. So I manually ran from a REPL and got a segfault:

julia> SymbolServer.symbols(env)

Seems like a duplicate of julia-vscode/LanguageServer.jl#1054, though this repo is maybe where it belongs.
