Crashes whenever it's about to output a code block

[Mouradif]

Using deepseek-r1-distill-qwen-1.5b-q4-0.gguf, I asked the model to generate code 3 distinct times. I could see the whole reasoning then something like "Here's the code for (whatever-I-asked-for):" then it crashes with

panicked at /Users/sebcrozet/.cargo/registry/src/index.crates.io-1949cf8c6b5b557f/web-framework-markdown-0.0.1/src/render.rs:408:18:
expected string event, got something else

Seeing that the panic seems to be in web-framework-markdown crate, I feel like it might have something to do with the model starting a triple-backquote code block. This only happens in that scenario and the crash occurs right where you would expect the model to start a code block.

Looking at the code from 2 months ago in web-framework-markdown (when the crate was published)

    /// extract the text from the next text event
    fn children_text(&mut self, tag: Tag<'a>) -> Option<String> {
        let text = match self.stream.next() {
            Some((Event::Text(s), _)) => Some(s.to_string()),
            None => None,
            _ => panic!("expected string event, got something else"), // <-- this is line 408
        };

        self.assert_closing_tag(tag.to_end());
        text
    }
