It seems to think chromium is on a different workspace (see the indicator to the left of the launcher item). Does changing to one of the other workspaces make it appear in the task switcher?

[Sami Sieranoja (sjs-a)]

Unfortunately I am unable to test this because the chrome icon reappeared on the task switcher after using the system for a while (around 10-30 minutes). I didn't use the workspace switcher at all.

I'm not sure if this issue is related, but if I move a terminal window from one workspace to another and then go back to the old workspace, terminal is still visible on the task switcher. But choosing it on the task switcher has no visible effect. Also the indicator tot the left of the launcher item is the same (solid triangle) on both workspaces. The terminal window does not cross the workspace border.

Status changed to 'Confirmed' because the bug affects multiple users.

it happened to me with gedit, firefox and chromium-browser

seems to happen when locking/unlocking anapplication from the unity bar.
