It seems that there is a bigger problem...

Whichever application is uninstalled, it leaves behind an empty installation icon on desktop. Only solution is to also remove the guilty application icon from /usr/share/applications/installer-extra directory.

Does anyone have any clue how to fix this? Otherwise, whenever i uninstall anything, i also have to manually delete the respective ghost .desktop file from the /usr/share/applications/installer-extra directory...
