[Mediawiki-l] Inexplicable Errors using Upload API in 1.16b3

I'm attempting to upload files to my wiki by way of the API. I'm using version 1.16 beta 3 installed on a CentOS VPS. I am using the API on my mac using OS X. Here is my command:

curl -b cookies.txt -F token="359d6add9d7d2d7f61c0e47e872d932b+\" -F filename="Test.txt" -F "file=whatever" " http://www.domain.com/w/api.php?action=upload"

If the token is incorrect, I get the appropriate bad token message. But when it's correct, I get this bizarre response:

<span style="color:blue;">&lt;error code=&quot;missingparam&quot; info=&quot;One of the parameters sessionkey, file, url is required&quot; xml:space=&quot;preserve&quot;&gt;</span>

Moreover, if I use this command:

curl -b cookies.txt -F token="359d6add9d7d2d7f61c0e47e872d932b+\" -F filename="Test.txt" -F file="@filename" " http://www.domain.com/w/api.php?action=upload"

I get this even more bizarre response:

<span style="color:blue;">&lt;error code=&quot;internal_api_error_MWException&quot; info=&quot;Exception Caught: Internal error in ApiResult::setIndexedTagName: Bad parameter&quot; xml:space=&quot;preserve&quot;&gt;</span>

Does anyone have any suggestions?

Thanks, Douglas
