[Bioc-devel] invalid PDF version and NULL vector errors in unchanged package

Dear Sokratis

What do you get when you run the package vignette on a current R-devel 
on your own machine?

Even if your code didn't change, that of R, or of packages your package 
depends on, will have changed and may challenge assumptions that you 
make in your code.

best wishes
