Weird display problem

My client send me a file with a display error.
In the attached file, there are a box object plus a line.
As you can notice, only the Top view shows the contour of the box.
When you hide the box and type _SelAll, Rhino selects the line object. The details tell me that it is a valid object with a length of 406 mm. Only after deleting it, Rhino shows the box well in all viewports.
What’s happening here?

Check out the line object - it’s pretty far out in space…



Thank you Mitch!
Splendid that you look further than I do. This makes it all clear.

Probably someone made an enormous move by typing in a large value.
