Fri, 10 Apr 2026 01:27:07 +0000 https://bugs.horde.org/ticket/7004 Can't save empty task list over WebDAV Steps to reproduce (using Nag from CVS so WebDAV works): 1. Create a task list in Horde. 2. Subscribe the URL in Kontact or another WebDAV/GroupDAV client. 3. Create a new task in the task list. 4. Check that the task is there in the web interface. 5. Delete the task in your client and let it upload the changes. Kontact displays "Unexpected error 400" and the server log contains "HORDE [error] [horde] Es wurden keine iCalendar-Daten gefunden. [pid 10097 on line 157 of "/usr/local/share/horde-webmail-1.1.1/lib/Horde/RPC/webdav.php"]" (No iCalendar data found.) Workaround: delete the task in the web interface.

The loop after the check won't get executed but this is not a problem. After saving from the client, the task list empty as it should be.
