After initial start, korganizer-mobile does not show any calendars. Shortly after the startup, the "Personal Calendar" appears. In the Actions flap Accounts section, "akonadi_ical_resource_0" and "Personal Calendar" are shown. The first one comes surprising and was not there in previous versions, i believe. Seen in version 4:4.5~20101001.1181693-1maemo4.1181469 .
Is this still happening for you? I can't reproduce here.
Hello! Sorry to be the bearer of bad news, but this project has been unmaintained for many years so I will be closing this bug.
