parity --help|x crashes

[SjonHortensius]

I'm running:

• Which Parity version?: 1.8.5
• Which operating system?: Linux
• How installed?: from source

This is a extremely minor issue, but parity segfaults and tells me to report this. parity --help|x (piping to any non-existing binary) will crash saying:

stack backtrace:
   0:     0x55fea5c3735c - <unknown>

Thread 'main' panicked at 'Error writing Error to stdout: Error { repr: Os { code: 32, message: "Broken pipe" } }', src/libcore/result.rs:906

This is a bug. Please report it at:

This issue was previously reported (#4295) and marked as fixed, but it seems this is broken again.

It's a rust bug and the upstream developer decided not to fix it.
