I'm considering to use lightspark for debugging AS3 projects on my Debian 7.8.
I'm hitting a problem though, this is the output:

ERROR: Unhandled ActionScript exception in VM SecurityError: SecurityError: not allowed to navigate up for local files

I am indeed trying to load local files in a higher directory. This works in the standalone adobe player.
Is there some way to set directories as a safe sandbox?

I start lightspark like this:

lightspark /path/to/file.swf -p parameters -s local-trusted

Thanks in advance!
