If you look through the code of net/imap.rb you'll see that there is no 
occurrence of "ERROR" anywhere. Nor in digest nor ssl. You'll need to 
look at your backtrace and actually debug where this is coming from.

Really hard to debug code without seeing it, but...

Generally when these things happen, it's because of passing in bad
references and so on. Make sure you are checking all error returns and
trapping the exceptions you can.

Break down the code to small enough components you can test each one
by itself (and test first, early and often!).

Are you stuck using 1.8.7? 1.9.x are *so* much better.

You can help us help you tremendously by showing us the real code and
the backtrace listings.
