+Subject: [PATCH] rhbz#2104545: Only call utl::IsYounger when its result is
+ actually used
+
+...as it may be expensive, or even throw (uncaught) exceptions (as apparently
+happened at rhbz#2104545, throwing some css::uno::RuntimeException while aMedObj
+was an sftp URL).
+
+The two branches in the if statement's condition that will now potentially call
+physObjIsOlder are disjoint (one for aMedObj being a file URL, the other for
+aMedObj being any WebDAV-related URL), so there is no chance that this change
+accidentally causes utl::IsYounger to be called more often than it used to be
+called.
