**Exact steps for others to reproduce the error**
Just import the file.
This files comes from Zbrush. It's a high dense mesh of 800Mb. If the error is sufficient for you to understand the problem? The file is quite big and is made of a bunch of objects, it's a character. Maya handles it well and imports, by the way.
If it's not possible for you to determine the problem without the file, i'll ask permissions to publish it.
