Event stream quits immediately with Chromium

[muni-corn]

Library version 1.1.2.

playerctl seems to follow events fine, but this library seems to crash with Chromium.

Running the events.rs example in the examples/ folder produces this output:

~ $ env RUST_BACKTRACE=full cargo run
    Finished dev [unoptimized + debuginfo] target(s) in 0.10s
     Running `target/debug/sandbox`
Showing event stream for player Chromium...
(Exit with Ctrl-C)

That's weird. I can't really tell where this happens from the backtrace; maybe the issue is inside the dbus crate?

Do the other examples work with Chromium for you?

[Mange]

Maybe this could be related to #50?

[djmaze]

Same problem here. Seems not to be fixed yet.

[Mange]

Have you tested the latest master commit or just the latest release, @djmaze?

[djmaze]

Right, only tested the release so far. Will have a try!

[djmaze]

Interesting. With master as opposed to 1.1.2, it seems to work!
