Reproduction steps

I was using a non-default theme.
When I tried to change it back to default by typing :theme , helix crashed.

Before this happened, I clicked UP / DOWN arrow key 2 to 3 times cuz I forgot that I have to use TAB key to switch between options.

~/.cache/helix/helix.log was EMPTY but I do have some screenshots

Environment

• Platform: Termux (Android)
• Helix version: 0.5.0

Can you produce a full backtrace by running RUST_BACKTRACE=full?

I have set it to full now. Did not know this before. I’ll try to reproduce the crash and update this issue. Thanks for reply

Let's close this out in favor of #1888 which has more discussion.
