Segmentation fault when creating image with text

First of all, thanks for the library.

I'm having trouble trying to create an image with text. The same command works in the official command line utility. If I remove TextOptions, then the Rust code also works.

Rust demo

use libvips::{ops, VipsApp};

fn main() {
    let _app = VipsApp::new("Test Libvips", false).unwrap();
    let image = ops::text_with_opts(
        "test",
        &ops::TextOptions{
            font: "Roboto 12".to_string(),
            fontfile: "roboto.ttf".to_string(),
            ..ops::TextOptions::default()
        },
    ).unwrap();
    // ops::jpegsave(&image, "test.jpg").unwrap();
}

An example of a working command

vips text test.jpg "test" --fontfile roboto.ttf --font "Roboto 12"
