"fdo#53280: Reset read-only UI after successful Save As" is a rather 
trivial fix for the annoying little regression 
<https://bugs.freedesktop.org/show_bug.cgi?id=53280> "FILE SAVE AS: Can 
not edit read-only file after SAVE AS" introduced into LO 3.6.0 via 
<http://cgit.freedesktop.org/libreoffice/core/commit/?id=b9ecec7c74687ed5a9470cffb7d02e0e6e83107e>
