I just found a mail body which is not decoded properly
by imap_qprint() (returning empty string), but is 
decoded the right way by quoted_printable_decode()

the string is the following (not including the ------ lines)
>Monsieur, A la suite de l'envoi d'un bon vert pour la 
connection =E0=20 resulb, nous n'avons toujours pas 
de nouvelles. Le payement a-t'il bien =E9t=E9 effectu=

That's not a bug. This is a malformed quoted-printable encoding (read FRC 2045 section 6.7). 

If you try to do imap_qprint("=\r\nE9") (which is found in line 3 of your example), it's not gonna work, and neither will quoted_printable_decode(). Both will print return "E9", and not the character encoded.

You can't see any output at all because don't even use "\r\n", but just "\n", which is not RFC compliant by itself (but nobody seems to care).

In short, this is not a bug, and the difference between imap_qprint() and quoted_printable_decode() is that one does not produce any result at all, while the other produces bogus result (although it does it's best to guess what you meant and fails).
