Comment 10 for bug 505600

I just had the same problem in the full release of 10.04 when I change the icon for an app in the menu editor it doesn't do anything to the icon used in favorites.

My research shows that the problem is that the .desktop files created for the favorites menu ( in ~/.local/share/applications) ONLY set the Icon[en-us]=/path/of/my/new/icon it does NOT however also edit the Icon=/path/to/old/icon

I posted my discovery on one of the other duplicates of this bug as well, I hope that this helps someone to fix this, because it really looks UGLY (especially when you make prism apps, and all it shows up as the launcher icon, YUCK)
