Bug Description

qmlscene based apps are recognised as a single app by Unity: in the launcher and alt-tab they appear as 1 icon that is a question mark. This is because Unity does not know anything but that the binary is the same (qmlscene).
The app discrimination is done by BAMF. BAMF could:
- differentiate the different apps depending on which qml file is given to qmlscene
- parse the --desktop_file_hint command line argument passed when launching the app and extract the desktop file from there
- OR be given the desktop file of the app via _NET_WM_DESKTOP_FILE

We agreed to go for the first & second options:
1) 'qmlscene' will be added to the list of well known launchers (like python, etc.) to BAMF
2) BAMF will parse the --desktop_file_hint command line argument passed when launching the app and extract the desktop file from there.

This bug was fixed in the package bamf - 0.5.0+13.10.20130725-0ubuntu1

  * BamfMatcher: correctly match QML applications launched with qmlscene
    or qmlviewer. (LP: #1180402)
  * BamfLegacyWindow: cache the window Exec string We might use this
    value multiple times during the BAMF execution, and we don't need to
    recompute it everytime. Caching looks a good compromise.
  * BamfMatcher: add support for the "--desktop_file_hint" exec
    parameter to override matching This is needed mostly by new Qml
    applications, but it allows to every app to override its matching by
    calling it with --desktop_file_hint file-to-use.desktop. (LP:
    #1180402)
