Gkrellm 2.3.0_0's mailcheck does not like SSL

Hi, I have been using for a while now gkrellm 2.2.10_0 and I just upgraded to 2.3.0_0. Everything seems to work fine, except for mailcheck. In 2.3.0 for some reason it starts to dislike imap-ssl connections. When such a thing is present, mailcheck fails to retrieve anything from the server. Note that imap-ssl worked fine in 2.2.10 and works fine with my email client. I don't even know how to diagnose it any further, so any pointer is indeed appreciated (especially given that I access all my mailboxes over imap-ssl). Many thanks in advance, Stefan
