problem with sent items in 2.2.4

[Kris von Mach]

Hi,

I am encountering a very weird problem in imp 2.2.4.

I have set sent-items folder to 'Sent Items' and the messages are not saved 
there, or anywhere else...

So I have tried changing the sent folder to 'Sent Item' and it works... 
Also 'Sent-Items' works. Why in the world would 'Sent Items' not work then?

Here are my relevant folders:

drwx------   5 vpopmail  vchkpw     512 May  1 16:58 .Sent Item
drwx------   5 vpopmail  vchkpw     512 May  1 16:59 .Sent Items
drwx------   5 vpopmail  vchkpw     512 May  1 16:58 .Sent-Items

I use vpopmail4.9.8-1 with courier-imap 1.3.5

I am using imp 2.2.4 with import-contacts-2.5.patch, 
statusbar-user-2.1.patch, and problem-email-2.2.1.patch

$default->folders                        = '';
$default->use_imap_subscribe             = true;
$default->show_dotfiles                  = false;
$default->save_sent_mail                 = true;
$default->sent_mail                      = 'Sent Items';
$default->postponed                      = 'Drafts';

/* Cyrus Configuration */
$default->personal_folders               = 'INBOX.';    /* i.e. INBOX. */
