 Replying to [ticket:2284 hcho]:

 > Can we fix this? Or can we opt to use the old init.sh, which I think is
 gone now?

 There's no reason to revert to init.sh, but we could replace prompt.py
 with the bash version (prompt.sh) from 6.x. The prompt script is only used
 if you're using bash as your shell, so portability isn't an issue.

 You can disable the fancy prompt with "unset PROMPT_COMMAND".

 The error could probably be avoided by wrapping the entire prompt.py
 script in a try/except block, but that wouldn't help with performance.
 Ignoring the signal wouldn't work reliably, because you'd have to import
 the signal module first, and any signal raised during that time would
 still result in the KeyboardInterrupt exception.
