Having the same problem.
Have you applied any mail contibs prior to upgrading (eg. upgrade to IMP 3.0 in 5.1.2, changing the default directories in 5.1.2 so that they appeared correctly in WebMail & Outlook, fetchnmail, etc.)? I have applied each of these, but nothing else I can remember.
Do you have anything in your boot.log (/var/logs/boot.log - specifically associated with horde)?
