If I click on Folder -> Subscriptions, and select my Sun IMAP mail account, I cannot manage my subscriptions without Evolution crashing with a NULL pointer dereference.  After the folder list comes up, clicking on a few folders results in a crash.  This is always reproducible on both Linux and Solaris.
