It happens some times, especially when HTTP client uses short boundaries
(for example libW3Perl based clients).

The basic boundary with LibW3Perl is 'OOO', and this is what happen when
the file 'toto.txt'.
toto.txt:
|  hello
|  there is a 000 sequence
|  in my file

The test request is the example file upload given in the php2 manual.
the result is :

<br>
<b>Warning</b>:  File Upload Mime headers garbled [equen] in
<b>/usr/local/www/htdocs/test/upload.php3</b> on line <b>1</b><br>
HTTP/1.1 200 OK
Date: Thu, 23 Apr 1998 08:54:16 GMT
Server: Apache/1.2.5 PHP/3.0b6
Connection: close, close
Content-Type: text/html
 
<H1> fichier charge : toto.txt</H1>
<hr><Pre>
 
hello
there i
</pre>

The error come from detection of the end or the next boundary which must
begin at the first character of the line and must be preceded with '--'.
This bug exists on both php/fi and php3.
