I was reading perldelta, and tried to access any bug report by hyperlink, e.g. [perl #128187], which shows me http://search.cpan.org/perldoc/https:#/rt.perl.org/Public/Bug/Display.html?id=128187
when mouse over. If I open it, my firefox shows strange url http://search.cpan.org/perldoc/https:#%2frt.perl.org%2fPublic%2fBug%2fDisplay.html%3fid%3d128187
and CPAN says: "Not found"
