CentOS - Aug 2011 - thunderbird cannot open attached pdf

I am using thunderbird on centos 6.
I get a message about cannot open the file as helper application
does not exist.

Which package needs to be installed for the pdf helper application?

Thanks,

Jerry

Dennis,

Odd, evince was installed, I then did a "yum reinstall evince"
and restarted thunderbird and clicked on the pdf attachment and same 
message.
