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

Appears as though two different icons are in use. One with the red wave form over the yellow (Launcher) and one without the red (Dash).

Yes, i search with the key Audacity in /root. There a lot of icon but only one is bad.
Bad:
/usr/share/app-install/icons

Good:
/usr/share/icons/hicolor/scalable/apps
/usr/share/pixmaps
/usr/share/applications
/usr/share/app-install/desktop
/usr/share/icons/hicolor (a lot of here)

The "bad" file /usr/share/app-install/icons/audacity.png is from the package app-install-data

The file in the package is menu-data/icons/audacity.png. I suspect this is autogenerated somehow, so merely changing it will not be an appropriate fix.

[Benjamin Drung (bdrung)]

menu-data/icons/audacity.png is probably generated from audacity.svg (from the audacity source package). audacity.svg is displayed incorrectly in eog, too. This is probably due to a bug in librsvg (filed as bug #1157471).

Bug still here in Ubuntu 12.04 and Ubuntu 14.04:
good icon in Unity Launcher
bad icon without red in Dash or in Ubuntu Software Center

@ Benjamin Drung (bdrung): Should be similar to bug #1157471.
