StartupWMClass gets ignored for .desktop files that are not in "*/share/applications" directory

[Iiro Laiho]

The StartupWMClass gets ignored for .desktop files that are launched by Nautilus from outside the "~/.local/share/applications" or "/usr/share/applications" directories

Steps to reproduce:

1) Download Tor Browser from the developer website
2) Unpack and execute it

Result:

Tor Browser windows get categorized as "Firefox" windows.

Excepted result:

Tor browser windows should be categorized as a separate app.

Workaround:

Run "cp '/path/to/start-tor-browser.desktop' ~/.local/share/applications" to copy the .desktop file to a directory from where Unity looks for it.
