Encountered error Unimplemented selecting Binder(<animation::PixbufSimpleAnim as glib::translate::ToGlibPtr<*mut <animation::PixbufAnimation as glib::wrapper::Wrapper>::GlibType>>) during codegen

[Gerschtli]

Hello,
in a travis build I received a compiler panic executing the command cargo tarpaulin --out Xml (tracking issue: xd009642/tarpaulin#186). Because I have no insights about tarpaulin, I can't provide more information as you can get from the travis build log.

I will post the important parts of the log down here, TIA!

$ rustc --version
rustc 1.33.0-nightly (14b96659e 2018-12-25)
$ rustup --version
rustup 1.16.0 (beab5ac2b 2018-12-06)
$ cargo --version
cargo 1.33.0-nightly (2cf1f5dda 2018-12-11)

Full output of command:

$ RUST_BACKTRACE=full cargo tarpaulin --out Xml

Tarpaulin finished
Error: TestCompileFailed

[Gerschtli]

I was able to trace the error down a bit. The bug in rustc occurs on this minimal example:

Cargo.toml

[package]
name = "example"
version = "0.1.0"
[dependencies]
gio = "0.5.1"

src/lib.rs

#[cfg(test)]
mod tests {
    #[test]
    fn it_works() {
        assert_eq!(2 + 2, 4);
    }
}

Reproducable by:
