System Information

Operating system:Ubuntu 18.04.1 LTS
Graphics card: GeForce GTX 960M/PCIe/SSE2

Blender Version
Broken: 2.80, 81ea815dcb, blender2.8, 2018-12-12 23:51

Short description of error

Blender crashes when selecting an entire collection and attempting to snap cursor to active.
Unfortunetly I was unable to reproduce the crash on a new clean file, thus I will attach the one which crashes hoping that it will help you isolate the problem.
I tested the same blend file, and same steps, on 2 different 2.80 builds from the same day, and only the second one crashed.

Exact steps for others to reproduce the

After opening the file, and without clicking on anything (looks like the issue might be related to the fact that nothing is currently active), do the following

Right click on the collection named Ball, and on the menu click Select Objects
Object -> Snap -> Cursor to active

After that, 81ea815dcb crashes at least on my system.

Please let me know if I can provide any additional information.

Cycles Material Ball v1.blend
Best regards,
Paolo

Confirmed with a build from today.

ob is nullptr below (from view3d_snap.c)

static bool snap_calc_active_center(bContext *C, const bool select_only, float r_center[3])
{
	Object *ob = CTX_data_active_object(C);
	return ED_object_calc_active_center(ob, select_only, r_center);
}

I can repro with the default scene as follows:

Start with default scene
Create a new collection (any name will do)
Create a cube in that new collection, and immediately delete it
- At this point no active object will be tracked
Right-Click on the original "Collection" which is still present and Select Objects
SHIFT-S -> Cursor to Active
- Crash
