In my setup, I happen to have an 'akonadi calendar' which as two 'Personal Calendars'. Whenever I try to add a Todo, I get this message: Error while saving akonadi calendar. Unknown error. (Append failed) Any idea what's going on? PS: recent upgrade from Squeeze, but wasn't using korganizer back then. -- Fayaz Yusuf Khan Cloud architect, Dexetra SS, India fayaz.yusuf.khan_AT_gmail_DOT_com, fayaz_AT_dexetra_DOT_com +91-9746-830-823
