cv2pdb: cannot add symbols to module, probably msobj140.dll missing

[Johnson via Digitalmars-d-debugger]

All of a sudden I'm getting this error. All I did was comment out 
a huge block of code so I could check something. The code 
compiles but the pdb conversion gives me that error ;/

Uncommenting out the code allows it to work again. I can't see 
why the code I'm commenting out would give that error ;/

Deleting the code also produces the same result.

It seems to be in use with GTK and event handlers. The handlers 
are completely isolated yet are somehow causing the problem.

You won't believe this, I'm sure, but

//Dialog.addOnDestroy((Widget w) {	});

causes the error! Must be some serious bug! Uncommenting allows 
the code to build fine.

I tried restarting visual D with no luck ;/
