I've had the same problem (Intrepid). I already had the PDF directory (755) from Hardy. My workaround: chmod 711 ~, do print to PDF, then chmod 700 ~ again.
I think that there are two connected problems.
1) cups-pdf fails to create PDF directory (bug #295318)
2) cups-pdf cannot navigate to PDF directory, because $HOME needs at least 001 (o=x) permissions
Oddly, even though cups-pdf needs execute permission to $HOME given to other (001), it doesn't need write permission to ~/PDF.
