REGRESSION: shell32: exception

The explorer crashes with the below exception since R53653 (Shell32 rewrite). (There are missing desktop icons in every revision with the explorer problem too, but I noticed the guidelines said to only report one bug.)

"ShellClasses exception

unknown Exception: 0x80004005
Context: ShellItemEnumerator::ShellItemEnumerator ()
Location: base/shell/explorer/utilities/shellclasses.h:1051"

In R53653, there is an application not found error when you try to open a folder with the Run box, but explorer will report the above exception if you open using browse files in the start menu. But in later versions like 53952, you get the exception regardless of how you bring it up.

I have a notion that part of the issue is a bad path or filename somewhere, but I am pretty confident that it is a shell32-related regression.

I noticed the problem running real hardware, and another has noticed this too:
