Thunderbird, New Message Counter Broken

[Dac Chartrand]

Running 13.04, latest updates synched to the timestamp of this post.

This was working a few days ago. I'm not sure what changed.

Steps to reproduce: Receive new email.
Expected: A number on the Thunderbird icon in the Unity Dash.
Actual: No number.

See attached screenshot.

This affected me after updating to Ubuntu 13.04.

quent57: Any ideas what changed? It's still not working for me.

Update:

If I drag & drop the Thunderbird icon a few pixels away from the Unity Dash, it springs back into position the message counter reappears.

If I don't do this however, it stays broken.

Exactly the same for me too.

I am affected by this bug as well. A very annoying bug that affects everyone using the default e-mail client should be high priority.

Problem is worse in Ubuntu 13.10.

"Pixel drag" workaround doesn't work anymore.

Counter number doesn't change after deleting a message.
