And on a serious note, a few flaws in MIME::Tools has just been reported
to Bugtraq (Florian probably knows this already ;) ), including:

	Problem 3: Incorrect concatenation of encoded MIME words.
	MIME::Tools does not remove the space from this example:

        	(=?ISO-8859-1?Q?a?= =?ISO-8859-1?Q?b?=)

	to yield (ab); instead, it yields "(a b)"  Some MUA's use encoded MIME
	words in the Content-Type or Content-Disposition fields.  Although
	this is specifically disallowed by RFC 2047, again, some Windoze mail
	clients may make the "obvious" interpretation and decode the words.

So, not a bug with RT, but the underlying module it depends on.
