I think the title says it all: defined(@array) is now deprecated in perl and this bug prevents generating graphical reports in bugzilla.
Hmm... it actually comes from this perl module: https://rt.cpan.org/Public/Bug/Display.html?id=79658 But unfortunately, fixing it like the way described in the bug report doesn't make the graph appear. I believe it was just a warning but was not preventing the function to display the graph. It must be something else but I have no more errors in my apache error log, so I don't know how to investigate further.
Summary: Bugzilla: chart.cgi: defined(@array) is deprecated at /usr/lib/perl5/vendor_perl/5.16.2/Chart/Base.pm line 233. => Bugzilla: chart is empty and not displayed
looks more something for upstream. you could also lauch the check script.
