The opendocs sysext has an option to be displayed as an backend module. If the extension taskcenter_recent is installed, it will load a list of recently edited elements.
This fails with a fatal error because the taskcenter API has changed.

However the opendocs module has already the necessary code implemented, so we don't need taskcenter_recent.

Solution: replace calls to taskcenter_recent with those from opendocs

1. Install opendocs
2. Enable the option to display the module
3. Goto module, see the list of open document, no recent documents
4. Install taskcenter_recent
5. See a fatal error in opendocs module
