Empty indicator applet in top bar

[Jenne Van Veerdeghem]

Next to the keyboard indicator is an empty spot. When this is clicked it just shows an arrow without anything else.

OP, can you list any changes you've made since installation including any apps you've installed?

[Danielle Foré (danrabbit)]

Can you also possibly include a screenshot of the issue?

This also affects me, here is a screenshot.

Hey Antonio,

Could this be the keyboard indicator?

[António Pereira (shaxine)]

Hello Zisu Andrei,

I highly doubt it because I uninstalled "wingpanel-indicator-keyboard" from the system. (I didn't enjoy the extra space)

And this bug it's not consistent as, sometimes it isn't there and after a update or a killall wingpanel it reappears.

[António Pereira (shaxine)]

After running wingpanel on debug mode I got the following output:
Could it be the "Sample Indicator"?

[António Pereira (shaxine)]

For some unknown reason I can't reproduce this bug anymore since the last few updates.
Jenne Van Veerdeghem, do you still suffer from this bug?

[rootsandculture (ivantutavac)]

This affects me too.

I think this may be related to adding extra indicators, eg: on the guest session this bug doesn’t appear by default, but in my session (where I have transmission, megasync and glippy loading at startup) always appear.

Note: I can reproduce this in the guest session by loading extra indicators and restart wingpanel.

[Cassidy James Blaede (cassidyjames)]

I have noticed this as well. I have Dropbox, TeamViewer, MEGA, and InSync installed on the machine I have seen it on. Those each have their own Ayatana indicator.

It's possible it only appears after closing one of those apps, but I'm not 100% sure about that.

[David Hewitt (davidmhewitt)]

Can anyone confirm if the following branch resolves this?

It resolves it for me, but there may be different problems at play here.
