--- Comment #4 from M. Raymond Vaughn <nethers...@gmail.com> --- The problem appears to have more to do with akonadi, kmail's backend, than kmail itself. If akonadi tries to synchronize a very large remote IMAP folder, it can become unresponsive; when this happens, kmail will wait indefinitely for a response from it. Killing akonadi and restarting it appears to temporarily resolve the issue. -- You are receiving this mail because: You are the assignee for the bug.
