I have attached a fix for this problem.
The patch changes php_quot_print_decode() in ext/standard/quot_print.c
so,
that it accepts the lowercase hex digits a-f.
This function seems currently only used for mime header decoding
according
rfc2047 in ext/iconv/iconv.c
However rfc2045 defines lowercase characters as illegal, but allows to
recognize
them as the corresponding uppercase letters in decoding.

Description:
------------
iconv_mime_docode() doesn't handle lowercase hex digits in Q-encoding.
According rfc2047 hex digits should be in uppercase, but it must not be
in this way.
Example:
=c3=bc - gives error
=C3=BC - works
Test script:
---------------
<?php
error_reporting(E_ALL);
echo
iconv_mime_decode('=?utf-8?Q?Nachricht_=c3=bcber_Kontaktformular_www.inexio.net?=',
0, 'UTF-8') . "\n";
echo
iconv_mime_decode('=?utf-8?Q?Nachricht_=C3=BCber_Kontaktformular_www.inexio.net?=',
0, 'UTF-8') . "\n";
?>
Expected result:
----------------

Actual result:
--------------
Notice: iconv_mime_decode(): Unknown error (25) in /usr/home/dm/test.php
