System Information
Windows 7 , Nvidia Quadro 2000

Blender Version
Broken: 2.69.0 (r60995), 2.69 nightly e7f3424 (probably many more, but these were tested by me)

Calling operator bpy.ops.view3d.view_selected from a python script with overriden context crashes Blender.

Exact steps for others to reproduce the error:

Open attached .blend file view_selected_crash.blend and run the script in the text editor
or

Start from default Start-Up File
Add cube
Switch to Scripting window layout
Create new text block

Paste the following script and run it by clicking on the Run Script button

  import bpy

  for wm in bpy.data.window_managers:
      for win in wm.windows:
          scene = win.screen.scene
          for area in win.screen.areas:
              if area.type == "VIEW_3D":
                  region = area.spaces[0].region_3d
                  override = bpy.context.copy()
                  override['area'] = area
                  override['region'] = region 
                  bpy.ops.view3d.view_selected(override)

Tested in Blender2.70rc1 - and I get this Python script error.

  Traceback (most recent call last):

  File "/d/view_selected_crash.blend/Text", line 12, in <module>
  File "/src/blender/release/scripts/modules/bpy/ops.py", line 186, in __call__
	ret = op_call(self.idname_py(), C_dict, kw, C_exec, C_undo)
        RuntimeError: Operator bpy.ops.view3d.view_selected.poll() expected a view3d region

      	Error: Python script fail, look in the console for now...

Did you modify the script to include the call to poll() or is it something that 2.70rc1 did internally?

When I call bpy.ops.view3d.view_selected(override) in the script above, I receive True.

Edit: With 2.69, that is...

I downloaded 2.70-RC1 and let the following script run after selecting the cube. It features both poll() as well as calling the operator.

Blender 2.70-RC1 crashes, too.

import bpy

for wm in bpy.data.window_managers:
    for win in wm.windows:
        scene = win.screen.scene
        for area in win.screen.areas:
            if area.type == "VIEW_3D":
                region = area.spaces[0].region_3d
                override = bpy.context.copy()
                override['area'] = area
                override['region'] = region 
                if bpy.ops.view3d.view_selected.poll(override):
                    bpy.ops.view3d.view_selected(override)
                else:
                    print("Inhibited by poll()")

This is a type mismatch, area.spaces- [x].region_3d is not a Region type.

Committed type check af84bf2d29
