Crash when trying to remove text from path

Summary:

After placing text on a path and then changing the text to a path, Inkscape will crash when I attempt to delete or remove the text from the path.

Steps to reproduce:

• open Inkscape
• create circle
• create text
• highlight both circle and text
• click flow text to path from menu
• adjust flowed text as needed
• change text to path using object to path from menu
• both of the following give the same crash:
• delete the text and path = crash
• select text and click unflow text from path = crash

What happened?

...both of the following give the same crash:

• delete the text and path = crash
• select text and click unflow text from path = crash

What should have happened?

...text should have been unflowed and been able to be deleted
