[maemo-developers] calendar-backend API: CCalendar's entries empty

[From: Filip-M. Brinkmann]

Hi Nicolai,

thanks for the valuable hint. The problem, as it turned out, was a
classical PEBCAK (*). In Qt Developer, I used user "developer" to deploy
on my N900. Therefore, this user's calendar was queried, returning zero
entries ;) 
So switching to "user" solved the problem.

However, thanks for your answer!

Best,

Filip
