mumble window cannot be found after minimized

Binary package hint: unity

When using unity, if the mumble window is minimized, it is lost permenently.

I'm running up to date natty unity desktop as of this morning (2011-03-17).

When I run mumble, if I minimize the window I can no longer find it anywhere (alt-tab or the launcher bar).

1.) launch mumble (I do so from gnome-terminal)
2.) connect to mumble server
3.) minimize mumble window
4.) try to find it.
