Crash - When textpath xlink:href points to path thats not in document.

Summary:

I created an svg entirely from Inkscape. I added about 5 paths to guide some lines of text. When opening the svg today, I see that 2 of the lines do not follow their own paths. If I try to put one of them on its path, or on another, nothing happens. If I try to remove it from its path, then Inkscape crashes.

If I remember well, at some point, some of the lines where not following their path, I mean, when I edited the path, the text would not bend over it, and remain with its last shape. Then I "unlinked" and "linked" again text and path, and it followed the path well. It may be related to this error.

Steps to reproduce:

• open Inkscape
• open an special svg that I don't know what went wrong on saving
• select one line of text on the top of the svg, out of place
• text → remove from path

What happened?

Segmentation fault

What should have happened?

When opening the SVG, the out of place text lines should have showed in teir place, following each one a different path they are assigned

I can share the complete example if it helps to understand how this situation was created.
