Mozilla 1.4/Opera 6.12 & Mime Types

[Gerard Samuel]

In particular, application/octet-stream and application/x-shockwave-flash.
I have a php script that uploads files, checking for allowed filetypes 
by its mime type.
It was put into action some months ago, and today, I notice its not 
allowing flash files.
The script is looking for application/x-shockwave-flash mime types, and 
Mozilla/Opera is
reporting application/octet-stream.
Konq 3/IE 6/Mozilla 1.4 (windows)/Opera 7 (windows) is reporting the 
correct application/x-shockwave-flash (according to info,
I found around the net)
Im wondering if there are any known problems with the FreeBSD builds of 
mozilla and Opera
with respect to reporting a file's mime type?

Any pointers/tips would be welcome.
Thanks...
