When icon theme does not exist, because of erasing the currently used icon theme, the launchers will display no icon, at all, instead of an icon of invalid-path-icon (I do not know which it is in the icon map of gtk). The menu entries of Xfce menu do display the "invalid-path-icon" icon upon icon theme deletion which is currently used.
I use Xfce 4.6.2
Mass-reassign all bugs from florian@ to goodies-dev@, thanks for the maintenance work! (and sorry for the bugmail spam..)
Is this still reproducible?
Now, it displays black shape of sun (see screenshot), instead of a red X inside a white file icon.
