[pmwiki-users] warning with attachtable

I think this counts as a bug in the cookbook.

Attachtable tries to do its best to figure out the MIME type of a
file; first it looks for the two PHP functions that can provide this
(finfo_open & mime_content_type) and if those fail it tries to exec()
'file -bi $filename' which is a standard *nix program for figuring out
the file type.

In your case your PHP is set up to disallow exec() calls, which
produces the error you encountered. This is probably a PHP safe mode
issue, but I can't verify that since none of the servers I work with
have safe mode enabled.

I've added a check for safe_mode in the update to the recipe I'm
working on, should get that on pmwiki.php in the next day or two.
