With rails 3.2.1, mail 2.4.1, trying to process an email coming in in Shift-JIS encoding:

this seems to avoid the exception:

This is still an issue for me in 2.4.4 - the patch from mreinsch works for me

@mikel if #347 is fixed, I think this is fixed now.

Now I am using mail-2.6.1."shiftjis.eml") is ok.
But the error is still reproducible only when using

By the way,
is NOT Shift-JIS email. It is an ISO-2022-JP (JIS) mail. They are both japanese charset but different charset.

If you want to get a shiftjis email, please let me know.

@kizashi1122 would you open an issue with your ruby version, ruby engine, and a failing test, please?
