Worked: (optional)

Short description of error

Its possible to use dyntopo eyedropper to sample detail size even if dyntopo is off
Doing so results in sudden crash
dyntopo crash.mp4

Exact steps for others to reproduce the error

Go to sculpt mode
make sure dyntopo is off
Go to dyntopo and change to "constant detail" to make eyedropper appear
use the dyntopo eyedropper to sample anywhere on the mesh with dyntopo off
Crash

Yes, I can confirm that. In Blender 2.81 it is not possible to use the eyedropper when Dyntopo is off.

@PabloDobarro It seems this issue was introduced in 47645a8db6 and caused by a change of the poll function in SCULPT_OT_sample_detail_size. Previously the picker was properly disabled.
