Error undoing/redoing change: System items can't be logically linked

[cnewtonne]

Hi all ...
I'm able to reproduce the error 'Error undoing/redoing change: System items can't be logically linked'

Here's how ...
1. Create a rich text info item containing days of week under 'My Data'. First child of the tree root.
2. Verify options / split text on separator is checked.
3. Verify separator text has null value
4. Highlight the above info item and go item / split
5. Do control + z to undo
6. Should get the above error
