Now I have found the cause of this problem:
There must be something wrong witch weekly recurrences of calendar events.

When I enter a calendar event that repeats every week, it seems to come 
to a buffer overflow in the procedure. It does not matter whether I 
define an end or not for this recurrence.
After saving the event the browser hangs. Reloading the page does the 
problem described above: No calendar events are shown.

After deleting this calendar-event record using phpMyAdmin everything 
works again.

It seems that this problem occurs only with weekly recurrences.
There is no problem with daily or monthly recurrences.

What can we do?
