 It's hard for users to determine what activities could be deleted t
 recover some space.

 A size column could be handy, but computing the size synchronously would
 freeze the UI for too much time. One possible solution would be spawning a
 command line such as

   du -s Activities/*

 and parsing its output asynchronously in the parent process. This is very
 easy to do with glib.spawn_with_pipe() and I/O completion callbacks. tch
 did something similar for the backup/restore function.
