- Blender version with error, and version that worked ---

2.66.0 (r54697) 64x
no known working previous version

- Short description of error ---

Using a mixture of the TAB shortcut and the spacebar context menu to switch modes causes a crash, with no crash handler appearing (e.g. WER does not appear)

- Steps for others to reproduce the error (preferably based on attached .blend file) ---

Press Spacebar and type "vertex paint", then press enter on "Vertex Paint Mode"
Press spacebar and type "weight paint", then press enter on "Weight Paint Mode"
Press TAB; observe exit%%%

%%%This part of our code got convulated in the past.

ob->mode is a bitflag, allowing to have every mode bit set.
but still there's an object->restore_mode to switch back to previous.
object_edit.c:object_mode_op_string() is not checking for the flags, except for editmode
the set_vpaint code disables wpaint, but vpaint not for wpaint.
also sculpt mode keeps all the other paint options on in ob->mode.
the view3d header menu for modes probably thinks completely different about it too.

I think there's too many people having different ideas for how it should work! This has to be handled. Need campbell's advice for it.
