Short description of error
A corrupt Push brush is created when I undo a Draw -> Sculpt mode change.

Exact steps for others to reproduce the error

File > New > 2D animation
Change from draw to sculpt mode
Edit > Undo (the mode changes back to draw mode)
Change again to sculpt mode as before
A new corrupt Push brush has appeared called F Push (instead of F Push Stroke), and is selected. It has no thumbnail. It is missing the usual UI elements of the Push brush, like strength. See screenshot.

This is due the Undo of the settings of the brushes. The first time you change to Sculpt mode, the brushes are reset, but when you undo, the mode is undo, but also the brushes. This bug is only the first time you Undo. As soon you cannot undo the first change, it works.

I'm going to try to tag in some way the reset to avoid this situation.

@ideasman42 Could you help me with this? Actually, when you enter in Sculpt mode, the brushes are checked and if something is missing, the brushes are created. Also, in the versioning of the template, the brushes are set. The problem is when Undo, the brush in the tool gets wrong.

I have been looking at the function gpencil_sculptmode_toggle_exec, and I call to the reset and to BKE_paint_brush_set to set the right brush, but for any reason the brush is not set.

For those who have this problem, there is a simple workaround: click Reset All Brushes (as suggested before by Antonio Vazquez)
