If the iconv handle is -1, then dont try and convert (crashes
2000-05-03 NotZed <NotZed@HelixCode.com> * camel-mime-utils.c (rfc2047_decode_word): If the iconv handle is -1, then dont try and convert (crashes unicode_iconv?). (rfc2047_decode_word): Use alloca for variables instead of g_malloc - by the rfc they should always be short. (rfc2047_decode_word): If we can't do the charset conversion, undo the quoted-printable/base64 at least? Should probably convert unknown characters to the utf-8 unknown character. svn path=/trunk/; revision=2774
