Tony MOREHEN reported a new bug.

Summary
-------

gb.desktop's GetDataDir() sometimes returns incomplete information

Type             : Bug
Priority         : Medium
Gambas version   : Unknown
Product          : Unknown


Description
-----------

When a Gambas program is run on a distribution that does not support the freedesktop specification or with a restricted environment (ie started through the Exec process function), GetDatDir will only return $HOME/.local/share.  It will not include /usr/local/share or /usr/share.

The GetDataDir code:
Public Sub GetDataDir() As String[]
  
  If Not $aDataDir Then
    $aDataDir = Split(Desktop.DataDir, ":", "", True)
    $aDataDir.Insert(Split(Env["XDG_DATA_DIRS"], ":", "", True))
  Endif
  
  Return $aDataDir
  
End

Desktop.DataDir returns the contents of $XDG_DATA_HOME or $HOME/.local/share if $XDG_DATA_HOME is missing
Similarly, the next line should insert the contents of $XDG_DATA_DIRS or [/usr/local/share, /usr/share] if $XDG_DATA_DIRS is missing.
