Gallery 2.3 bug? Itemdelete (album/singles)

Gallery 2.3 (latest nightly build - check for update today)
Couldn't find this problem, maybe it's already a known issue?

Ok here it is I am in an album then I have these options:

Delete album
Delete items

I choose Delete items. in the Delete items window the sidebar is still visible with the Delete album option. So I click (in the delete items window) Delete album...and I get a security error

Error Detail -
Error (ERROR_BAD_PARAMETER) : Class ItemDeleteSingleView not defined in core.ItemDeleteSingle
in C:\xampp\htdocs\gallery23\modules\core\classes\GalleryView.class at line 194 (GalleryCoreApi::error)

IE7/Firefox(2.0.0.10)/Safari doesn't matter actually which one I use got the error with all the browsers.
I think it happens in any album EXCEPT root/main. See pic where the link is that causes the prob.

All pictures are uploaded with Gallery Remote, and preformated to fit 800x800 envelope.

Any suggestion are appreciated.

Ok. So far. Today I managed with the same problem and, after I while, I found a serious error.

The developers messed up some files and lost some.

The missing files are:
/modules/core/template/ItemDeleteSingle.tpl
/modules/core/template/ItemDeleteConfirmation.tpl
/modules/core/ItemDeleteConfirmation.inc

Also with corrupt content is the file:
/modules/core/ItemDeleteSingle.inc

The reason why that happens -- They can't decide whether JavaScript is good or not. ;)

So just copy these named files to your location and you are happy again.

possible archive that contains all files you need

Hope you can enjoy your gallery2 again.
