I know what you're talking about :(

A more recent version of iconv might help:
System: Darwin 8.10.0 (Power Macintosh)
ncurses: ncurses 5.4.20041023 (compiled with 5.4)
libiconv: 1.11
libidn: 0.6.12 (compiled with 0.6.12)
Also you probably can reduce the /probability/ of this happening
by adding the following to your muttrc:
set assumed_charset="cp1252"
charset-hook ^unknown-8bit$ cp1252
charset-hook ^x-unknown$ cp1252
charset-hook ^x-user-defined$ cp1252
charset-hook ^us-ascii$ cp1252
charset-hook ^iso-8859-1$ cp1252
charset-hook ^iso-8859-8-i$ iso-8859-8
charset-hook ^gb2312$ gb18030
But I still believe that Mutt should not just *freeze* in case of
an iconv failure, but give the user some means to isolate the
message (including removing it from the mailbox) ... and then you
still need to pray that Alain Bench is around to give you some
ideas how to handle these messages ;)
