eric pushed a commit to branch xfce-4.10
in repository xfce/xfdesktop.

commit 27b81befc1a6d12767822dbde3534beab2db81f3
Author: Dennis Tomas <den.t at gmx.de>
Date:   Sat Apr 20 13:21:45 2013 +0300

    Fix HTTP URL performance issue / wrong action proposed
    
    - only check "file" URLs for move/copy
    - adding an optional output parameter "suggested_action" to the
    icon's allowed_drop_actions()
    
    The suggested actions are:
    
    folder:   move if writable else none
    volume:   copy if writable else none
    file:     copy (run) if executable else none
    trash:    move
