in reply to sysread() is deprecated on :utf8 handles
I quote from the reference above:
The best thing to do would be to backport the upstream patch that make +s Bugzilla use File::Slurper (which doesn't have the issue) instead o +f File::Slurp.
I have not tested, so I can not say 100% will work but you can update us after applying it. :)
Hope this helps, BR
