Inbox list not refreshing

I am currently running a the latest public CVS version of roundcube, and I have had problems with the list of messages in the inbox not refreshing.
Here is my test case, perhaps someone can confirm if this is happening to them too or not.

I send a test email to myself so it should show up in the inbox. I log into roundcube, and I do not see it in my inbox. I see older messages, but not new ones. I can click on the inbox folder, and it still doesn't show up. I click on the "Mail" button in the toolbar, and it still doesn't show up. If I click a different folder, and then click the inbox again, finally it refreshes and I see the new message.
