Dia does not have a panel icon in Unity. It defaults to the ugly "?" icon.

I'm using Ubuntu 13.04 and this problem seems still seems to be around.

If I run dia from the console I get a dead icon saying "Loading...". The icon's context menu (e.g. Quit) does not affect the running program. Dia has another icon which is correct. If I pin that to the launcher it will not start dia on click.

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

Same as #2, but icon context menu works (when the program is running).

Of course invisible in Dash search.

Confirmed this.
I can't find Dia in Unity Dash, now I have to run it in command line.
Anyone could kindy fix it?

Same problem here.
