Description

System Information
Operating system: Windows-10-10.0.18362-SP0 64 Bits
Graphics card: Intel(R) HD Graphics 4000 Intel 4.0.0 - Build 10.18.10.5100

Blender Version
Broken: version: 2.82 (sub 7), branch: master, commit date: 2020-02-12 16:20, hash: rB77d23b0bd76f
Broken: version: 2.82a, 2.83 latest experimental build.
Worked: 2.80, 2.81, 2.81a.

Short description of error
Typing "sy" (for symmetry) on the search bar when the viewport is empty crashes blender. Blender still crashes when there are lights and cameras visible but doesnt crash if one of the other object type is visible.

Exact steps for others to reproduce the error

  1. Open blender
  2. Hide or delete all the objects, so the viewport is empty
  3. Open search bar
  4. Type sy

Works with default startup file

sculpt_no_multires_poll() should check SCULPT_mode_poll() first and short-circuit if it returns false. It has to be ensured that ob isn't NULL when attempting to dereference it.
