GLib-GIO-WARNING **: Received property Rate with type y does not match expected type d in the expected interface

[orschiro]

Dear @acrisci,

Thank you for your work!

I just installed the latest deb package on Ubuntu 16.10 to test it.

Can you help me with the following error?

Yours,

Robert

Hi,

This probably means your player is not imlementing the dbus interface in the way that is expected.

What player are you using?

Dear @acrisci,

I experienced this with https://github.com/Quacky2200/Spotify-Web-Player-for-Linux

Any update on this issue? I'm facing the same problem with mopidy

[acrisci]

This is a bug in the javascript implementation of the dbus library. Fixing it there is on my to-do list. It's probably too severe to put a workaround in playerctl.

@acrisci One of my scripts broke because of this. I ended up redirecting the stderr to /dev/null as a workaround

[acrisci]

Why are you listening to stderr? It's only supposed to be for diagnostic messages like that.

[fa7ad]

@acrisci I wasn't specifically filtering out which output stream to capture. just capturing the output altogether and then running other stuff based on that.

[fa7ad]

@acrisci I'd love to help with the JS bug, where should I be looking? I wanna have a crack at it while you're busy 😄

[acrisci]

Now I can't find the exact issues. The library they use is this one I think: https://github.com/sidorares/dbus-native

The issue was the library was guessing the types and guessing wrong.

Support that issue if you want it fixed.
