Short description of error

Selecting particle system as Dynamic paint Brush crashes Blender.

Exact steps for others to reproduce the error
Based on the default startup or an attached .blend file (as simple as possible).

Open default factory settings file in Blender 2.8 Beta.
Press Delete to delete the cube that is selected by default once a new file is opened.
Press Shift+A to open the Add menu and select a Plane.
Press Tab and S and 8 to scale the plane in edit mode.
Press F3 to open the search menu and search for Subdivide.
Click on the popup-menu in the bottom-left corner and expand it and type 60 to number of cuts.
Tab out of the edit mode.
Shift+D to duplicate and lift mouse to drag a copy of the plane above it (constrain Z-axis by pressing Z).
Top plane is selected now. Go to particle systems, add a new particle system and then go to Dynamic Paint and create a brush.
Set the brush source as Particle system - ParticleSystem.
Blender crashes and closes.
(Note: I tried also to add the lower plane as a Dynamic paint canvas before setting a new brush, but it didn't help. So basically particle system brushes are broken.)

Otherwise I'm very happy for the beta :D

I've followed your instructions and came up with this:
part_dyn_paint.blend

But setting the brush doesn't crash for me.
Is this still and issue for you?

Hello. No, I think that bug was either fixed already a week after I reported it or then I just had some other problems with my computer - either way it worked fine just for my Xmas card renders :D

PS.
Now there's another bug/or feature I've discovered relating to DynPaint. I haven't reported it yet since I'm not sure how it's supposed to behave, but basically I tried to bake displacement dynpaint into one canvas and color dynpaint onto the same mesh as another canvas. After baking, "viewport render animation" looks correct and yields correct results but the actual "render animation" -button removes the firstly baked dynpaint info from the renders. So the animation must be rendered with the viewport settings in order to get it right. I've seen tutorials on Youtube where they claim that "viewport render animation" works correctly always but "render animation" doesn't - and it sounds like a big issue as well so either it's a limitation or someone's probably working on it? :D Or should i report this thing as a bug?
I'm so confused about this whole reporting bugs website and how I'm supposed to find if something's already reported that I might sound a bit dumb and obnoxious in these messages, sorry ^^'

Sure you can report it.
Just have a nice minimal .blend file and a nice description :)
