Describe the bug
When using tab-completion on a import of a non-existent file nix-repl crashes.
Steps To Reproduce
Crate a file like:
Open a repl and type:
When pressing tab for completion the repl crashes (and sometimes also the shell).
Expected behavior
Handling of that edge case in a more graceful manner so that it doesn't crash the repl and maybe prints a warning to the user instead or just does nothing.
nix --version
outputnix (Lix, like Nix) 2.90.0-lix
For clarity since when you said "crashes" I expected e.g. a segfault or something:
Also reproduces in Nix 2.18.2 and 2.22.1.
I'd consider the nix repl exiting a crash in this case since it doesn't with other faulty code.
