Ok, running the command line version of scribble I get the full trace -- and it's due to a missing latex package:
! LaTeX Error: File `skull.sty' not found.

I googled for that, found the sty file, but that's not enough. There are font related errors. Then I found that:
http://www.ctan.org/tex-archive/fonts/skull/

but that doesn't work either. The description of that package is "A font to draw a skull." --> why would that be needed for scribble?? If I let the error messages go (generated the tex file and then compiling myself), I get a PDF that looks quite ok to me.

Can someone explain me what this skull dependency is? what does it really refer to? 
(I doubt it is the "font to draw a skull"... unless that's the skull/lambda logo or something;))

Thanks,
