[O] Non-interactive export

[Simon Thum]

Hi all,

I have a server over which I sync my Org files and provide drops for 
other clients, chiefly iCal and vCard. Therefore I need non-interactive 
export.

Things recently stopped working however, and although I acknowledge it 
is likely not Org's fault maybe here I can find somewone more into lisp 
to help me out a bit.

In my logs I find, since it stopped working:

> Evaluate this gnuplot code block on your system? (yes or no)


Which stops the show, waiting for input. Emacs is started with -batch 
and is given an export script. This so far avoided such questions (from 
org-babel?) successfully. I have maxima blocks since ages and do not 
remember having seen this behaviour.

Does naybody have an idea what could be going on?

The machine does not even have gnuplot.

Thanks in advance,

Simon
