Patch.

Logic: show file size info if at least one selected file has GNOME_VFS_FILE_INFO_FIELDS_SIZE set.

String changes, unfortunately.

true. we should not display the size at all, that is obsolete.

patch works for me

I've been using this patch for weeks without problems

Can't go in atm due to string freeze, but looks like a good idea.

Here is a bug peek to make remember that the string freeze is finished and this could now be applicable. 

Just to make you remember before it pass to much time before being applied.

Thanks for the reminder. Commited.
