rishi:  I am seeing something bizarre with WK2.
rishi:  It seems to clear out the contents of the ~/.cache/gnome-documents/ directory.

We need to document that the default cache directory is g_get_user_cache_dir()/g_get_application_name(), and that WebKit will delete any files it finds there (since libsoup 2.50). Otherwise applications that try to use it for their own cache, like GNOME Documents, will have a bad time.

Bug #144048 has a better solution for this.
