Problem uploading files (possibly an OS X issue?)

Hello,

I am implementing uploadify in my rails apps and I currently have a similar problem as described in this old post (Problem uploading files (possibly an OS X issue?) - Rails - Ruby-Forum) with the same error message. This message occurs only when I try to upload a file when on a Mac and the apps being deploued on my hoster environment (Apache+fastCGI). Uploading from a windows environment works fine

Here is my configuration: Development: Mac OS X.6, with rails 2.1.2, uploadify 2.1.4, webrick --> everything is ok Integration: Mac OS X.6 on +flash 10 the client side and, rails 2.1.2+ Apache 2.2+fastCGI on the server side

I get this message only if I try to upload a file from a Mac, on a windows platform it work ok.

Any idea on the solution? Thanks in advance

Nicolas
