Comment 41 for bug 1165420

Bug still exists in Ubuntu 14.04. A year passed and still no changed?
This bug makes HUD just useless in most situations.
If there's not going to be any fix soon I would really need to consider switching to Gnome Shell...

Anyway I tried installing older package, with no luck really. HUD launched, but searching for anything just didn't work. Tried this one https://launchpad.net/~ubuntu-unity/+archive/daily-build/+build/4461354/+files/hud_13.04.0daily13.04.03-0ubuntu1_amd64.deb . Needed to remove libbamf3-1 from require dependences.
