Important: missing svn properties in new language xml files

[Jacopo Cappellato]

I've noticed that in the new xml files for ui labels the svn properies 
(svn:eol-style and svn:mime-type) are missing.

I have tried to set:
svn:mime-type=text/xml
svn:eol-style=native
but I got an error with the second one: "Inconsistent line ending style"

Any ideas on how to fix this?
