safe_mode is not a real security solution, that is why PHP has abandoned
it for their 6.0 release and Debian doesn't treat bugs in the safe_mode
restrictions as being security-relevant. There's quite some documentations
on its shortcomings around the net.

It will only have benefits in very specific environments, and there are
much better ways to isolate applications on a host. open_basedir may help
somewhat, but a good solution would be to use suEXEC + FastCGI to run the
application under a dedicated user.

If turning it off resolves the problem for you I suggest you do that and
investigate better avenues for isolation.
