Which calendar service or provider do you use, if any?

No response

Which sync adapter app do you use for calendar synchronization, if any?

DAVX5 and ICSX5

Steps to reproduce the bug

Items without title/SUMMARY are ignored by import. Other calendar-apps import them and display them with "no title".

I have one remote sync over ICSX5 which did not fill this field on all items. So I miss these events, because Calendar ignore them silently.

To reproduce you did not need ICSX5. Direct import fails too. Example:
termin-without-summery.ics.txt

Expected behavior

Please import these events and display them with "no title" or better with "NULL" ;-)

Actual behavior

The event with empty SUMMERY-field is not imported.
