I was able to reproduce this bug on OCCT 7.0.0
I'm often go into this bug, most of the time input file comes from Rhinoceros.
This bug also impact FreeCad and Salome.

Dear bugmaster,

it is not a bug, please close the issue.

Some details:
The file contains only a representation with one line without any topology entities like edges or vertices, and there are no other limits for this line, so the described result is the right behavior.
