Saving meeting notes blueprint with same name causes fatal error

When trying to save a Meeting notes blueprint with the same title, it will throw the usual error 'page with the same name already exists.....'
If you try to add more characters to the title to make it distinct it will throw the following critical error:

Repro steps:

1. Create a page from the meeting notes blueprint without modifying the title.
2. Create a second page from the meeting notes blueprint and try to save it without modifying the title. The error message saying a page already exist with the same title appears.
3. Modify the title and try to save. The stack trace appears.

The bug does not appear if you modify the title before you try to save it.
