BincIMAP Search Patch

[Jim Pingle]

Is there anyone else around that is currently using BincIMAP? I have a
BincIMAP server I'm forced to deal with in one setup, and the search feature
fails in the default configuration, because BincIMAP doesn't understand
UTF-8 and chokes when RoundCube sends the search query with UTF-8 specified
as the charset.

I have a patch that fixes this for me, but I'm sure it could use some more
testing/comments/whatever.

The ticket for this is #1483855

The patch is on the ticket:
http://trac.roundcube.net/trac.cgi/attachment/ticket/1483855/bincimap_search_fix.2.diff


Basically, if the search fails the first time it retries the search without
a charset specified. Assuming I read the code right, this should only happen
with a server error, not just an empty message set. (Another pair of eyes
might help verify that...)

Thanks,
Jim
