On my Chromium Launcher Icon a count of 4 is displayed. I have two Chromium windows with several tabs open.
A count with progress bar was always displayed when downloading. Therefore I checked this first but there is no download going on in any of my open tabs, and other than with downloads there is no progress bar now.
Here is 12.04 LTS amd64 running updated Chromium 23.0.1271.97 (precise-updates).
What would be the purpose of this count on the Launcher?
