[Inkscape-user] Patterns and shadows not exported to pdf

Hello,

I got a weird problem and wonder: I have some objects filled with patterns as well as some shadows. I do not manage it to export everything to pdf. My objects do not contain any pattorns or shadows. I avoided to work with opacities as i read somewhere, that transparency is not valid in pdf. But still, my patterns do not contain any transparency and a shadow only blurs (or is bluring connected to opacity)? Anyway, even when I eface the shadows, my patterns are still not exported.

Using Inkscape 0.46 on ubuntu gutsy.

Does anyone have an idea? I definetely need my files in pdf-format...
