[Dancer-users] Use of uninitialized value $val

I have started getting the following in my Apache error logs Use of uninitialized value $values[0] in join or string at /usr/local/lib/perl5/site_perl/5.12.1/Dancer/Route.pm line 79. I can't recall doing anything special that has started causing this. Doesn't seem to affect the web site, but I would like the error to not occur. -- Puneet Kishor
