After upgrading a particular system from 13.10 to 14.04 there are a few items in the launcher portrayed with a question mark:
This is not the old problem of windows mismatching applications. The icon is always rendered this way, no shadow icon is created when the application is running and it gets the visual semantics and behaviour as any other functioning launcher item.
It is neither a missing icon or a wrong icon path. Following some shell output regarding one of the applications concerned:
$ cat /usr/share/applications/eclipse.desktop
[Desktop Entry]
Type=Application
Name=Eclipse
Icon=/usr/local/eclipse.kepler/eclipse.png
Exec=env UBUNTU_MENUPROXY= /usr/local/eclipse.kepler/eclipse
Terminal=false
Categories=Development;IDE;Java;
$ ls -la /usr/local/eclipse.kepler/eclipse.png
-rw-r--r-- 1 lads lads 53556 Jun 11 19:00 /usr/local/eclipse.kepler/eclipse.png
What could then be the cause?
