I'm running pear.horde.org/Horde_Imap_Client-1.0.9 - installed with  
Horde 4.0.7 and IMP 5.0.8 two days ago.

For example, I'm having problems with folder name "Nytår"  
("Maildir/.Nyt\&AOU-r/").

However, another strange problem has appeared lately. When I have a  
mail that IMP doesn't like, it will not only refuse to show the mail.  
It will also give the "Unexpectedly disconnected from the mail  
server." error when trying to access the page on which the e-mail is  
located. I can go to previous page and next page, but the page itself  
can't be viewed. This might be related to ticket 10169, which was  
rejected (and unresolved).

I use UTF-8 everywhere on my system, which is a pretty clean CentOS  
5.5 installation. PHP (5.3.6) is compiled with:

--with-iconv
--enable-mbstring=all
--with-gettext

Other than that I use a custom built libxml2 (version 2.7.8) without  
any configure options set, i.e. quite straight-forward.

So I'm a bit puzzled, but don't really know where to look.
