[horde] ghostscript

[LALOT Dominique]

Hello,

I get lots of warning in apache error_log due to ghostcsript running.
Complains abour various problems in pdf files.
I'm rather worried about security. ghostscript is a big piece of code and
is called via a shell call. If I remove it, i get: sh: gs: not found

How can I disable the use of ghostcript in horde. If not, is there a way to
put garbage to /dev/null instead of error_log?

Thanks

Dom
