Broken Launcher Icons in Xubuntu Classic Panel Dock

[Wes]

Legacy launcher icons for programs that are no longer installed, including the Ubuntu Software Center, AbiWord , GIMP, and GMusicBrowser are still present in Xubuntu 16.04 live session when the Xubuntu Classic Panel Theme is set. Clicking the icons will display an error message box "Failed to execute child process "/usr/bin/<packagename>" (No such file or directory)" , since those applications are no longer packaged by default in 16.04.

To reproduce, go to Settings -> Xfce Panel Switch , select "Xubuntu Classic" , click the apply configuration gears icon , and look at the dock on the bottom of the screen.

Find attached screenshot.

Two improvements that should be made here:
1) The more obvious one, the default launchers need to be updated for 16.04+
2) xfpanel-switch should be able to check if an executable exists before adding its launcher to the panel.

Fix committed: https://bazaar.launchpad.net/~xfpanel-switch-dev/xfpanel-switch/trunk/revision/108

This change validates imported launchers, resets stored xfce4-panel settings, and no longer dies when the panel is not running.
