Looks like KAddressbook adds the same mimetype twice to the new Collection, 
which breaks some constraints in the SQL database when Akonadi tries to create 
the collection. It's a bug in Akonadi, I'll fix it asap [0].

Looks like a bug in the IncidenceEditor, added to Phabricator [1].

As of now, no. There's a known limitation in Akonadi that I'm working on fixing 
for a long time now. Basically when uploading an Item to the backend storage 
(IMAP, Google, EteSync server etc.) fails (and if the Resource calls 
'cancelTask()' instead of 'deferTask()'), Akonadi will never try to do upload 
the Item to the server again and it will only exist on your computer.

Right now, if the error is in any way recoverable, the Resource implementation 
should either try again (without letting anyone know), or it should at least 
deferTask() and try again later.

There's no way to hide the item from the user, since that would mean the data 
that the user has create would be in no way reachable to the user anymore.

I hope to be able to address this issue at some point soon ;)
