Philipp Oeser (lichtwerk) triaged this task as Confirmed, Medium priority.

Can confirm this, it is the curve objects causing this.
Just adding a curve in an empty scene causes the same crash...

CurveCache (ob->curve_cache) is NULL.
BKE_displist_make_curveTypes is never called (but should be?)

Side data, hiding the object BEFORE making the collection visible will not cause a crash if the curve is enabled after.

Here on my Ubuntu 18.4 GTX 750ti the same crash on adding a Curve.
I added the crash log; maybay that will help you figuring out what is wrong.
