These are some notes, for how to fix the problem, with the Select With option in user preferences.

The first patch would correct some keymaps.

When the Select With option is set to Left, this works though, some of the 3D view keymaps are still set to 'LEFTMOUSE'.

RNA_enum_set(WM_keymap_add_item(keymap, "SCULPT_OT_brush_stroke", LEFTMOUSE, KM_PRESS, 0, 0)->ptr, "mode", BRUSH_STROKE_NORMAL);
RNA_enum_set(WM_keymap_add_item(keymap, "SCULPT_OT_brush_stroke", LEFTMOUSE, KM_PRESS, KM_CTRL, 0)->ptr, "mode", BRUSH_STROKE_INVERT);
RNA_enum_set(WM_keymap_add_item(keymap, "SCULPT_OT_brush_stroke", LEFTMOUSE, KM_PRESS, KM_SHIFT, 0)->ptr, "mode", BRUSH_STROKE_SMOOTH);

WM_keymap_add_item(keymap, "PAINT_OT_mask_lasso_gesture", LEFTMOUSE, KM_PRESS, KM_CTRL | KM_SHIFT, 0);

RNA_enum_set(WM_keymap_add_item(keymap, "PAINT_OT_weight_gradient", LEFTMOUSE, KM_PRESS, KM_ALT | KM_CTRL, 0)->ptr, "type", WPAINT_GRADIENT_TYPE_RADIAL);

RNA_enum_set(WM_keymap_add_item(keymap, "PAINT_OT_image_paint", LEFTMOUSE, KM_PRESS, KM_CTRL, 0)->ptr, "mode", BRUSH_STROKE_INVERT);

RNA_enum_set(WM_keymap_add_item(keymap, "SCULPT_OT_uv_sculpt_stroke", LEFTMOUSE, KM_PRESS, 0, 0)->ptr, "mode", BRUSH_STROKE_NORMAL);
RNA_enum_set(WM_keymap_add_item(keymap, "SCULPT_OT_uv_sculpt_stroke", LEFTMOUSE, KM_PRESS, KM_CTRL, 0)->ptr, "mode", BRUSH_STROKE_INVERT);

These and probably some more, should be changed to 'ACTIONMOUSE'.

When the Select With option is set to Left, VIEW3D_OT_select and 'Select' keymaps are set to LMB, keymaps using 'Action' are set to RMB.

These keymaps should be syncronized to ensure both are swapped correctly, at the moment, some are not.

...

The other patch would re-add this (RMB select for paint modes) feature correctly.

I thought the best way to implement this, would be to limit the LMB/RMB toggle, by checking what mode blender is in, in the UI handler code.

i.e. Adding some conditional statement to WM_userdef_event_map, based on the 3D view mode, sculpt, weight paint, vertex paint, etcetera.

 }

 return kmitype;
