/* We really need access to a similar function to check whether a directory supports trashing and emit a warning if it does not!
The following function looks perfect, alas it is restricted to local files and to the implementation of GIO only:
gboolean _g_local_file_has_trash_dir(const char* dirpath, dev_t dir_dev);
See: http://www.netmite.com/android/mydroid/2.0/external/bluetooth/glib/gio/glocalfileinfo.h
Just checking for "G_FILE_ATTRIBUTE_ACCESS_CAN_TRASH" is not correct, since we find in
http://www.netmite.com/android/mydroid/2.0/external/bluetooth/glib/gio/glocalfileinfo.c
g_file_info_set_attribute_boolean (info, G_FILE_ATTRIBUTE_ACCESS_CAN_TRASH,
writable && parent_info->has_trash_dir);
=> We're NOT interested in whether the specified folder can be trashed, but whether it supports thrashing its child elements! (Only support, not actual write access!)
This renders G_FILE_ATTRIBUTE_ACCESS_CAN_TRASH useless for this purpose. */
