seemingly crashes with toots containing `gemini` protocol URLs

Hi,
whenever I moved in the TUI timeline to a toot containing a "gemini" protocol URL, I got a crash:

Log: https://sharer.woodpeckersnest.space/FuzE5/tUMOmaJa01/raw.txt

I couldn't spot any other similarities between the 2 toots which caused this, but I am not even 100% confident the issue is about what I reported here.

Thanks
