Errors when trying to upload media before saving network settings

[wp4j]

foreach warning due to unpopulated $mimes array and denial of uploads even when file types defined in network admin settings. This seems to happen because there is a disconnect between the defaults and what is actually present in the db (before the first save).

Should be noted that the site was installed programmatically using wp_install() so this may have something to do with it. I am giving this a major severity because the server path is disclosed from the foreach warning and the least that should be done is do an is_array() check on that $mime var and give a meaningful message stating that there are no mimes defined or something...

Could you provide a piece of code to reproduce the issue?

And please provide the full error (including file, line number) and/or full call stack.

Warning: Invalid argument supplied for foreach() in /wordpress/wp-includes/functions.php on line 1793

In current trunk, an error on this line implies there may have been an incorrect filter applied to ext2type. Closing, but feel free to reopen if code can be provided to reproduce the issue.
