Video/PPTX/PDF export is not working in source code compiling #722

Hello,

I don't know why, but when i'm trying to export my sozi presentation in PDF/PPTX/Video from building sources, the button "exportation" stucks and the presentation windows opens but never ends.

I don't see anything in the console nor in the debug tools.

Does someone has an answer for that ?

I'm using Linux Mint LMDE 6 Faye (v6.4.8) x64.
