i have this error when while maya starts loading maya , it works fine under root user (and can render) or when i remove MtoA and maya starts normally..

Can you post the full Arnold log (verbosity level Info) ?
What if you kick an ass file, does that crash?
I'd probably strace a render (for each account) and then compare.
