Crashes when switching input method

[sdvcrx]

Hello, I'm writing to report a problem I've been having with Goneovim. Every time I switch input method while using Goneovim, the application crashes unexpectedly.

Crash logs:

Additional details:

• I'm using Goneovim on MacOS, and input method is Chinese
• goneovim --version => v0.6.4
